Trying out auction-type recruitment in the labor market! ? The lemon market can be solved by establishing a trial period! !

Hello. I'm Watanabe Tenmei from Seito Medical School Clear File. This is another rewrite article. I'm going to rewrite the article titled "Is the 80:20 rule true? If the skills of the top 20% of employees were given to the remaining 60%, sales would more than triple. by Nada 20231004".

Recently, I thought that it would be good to conduct job hunting for workers through an auction system. In economics, there is a story called the market for lemons in the used car market. In the market for lemons, due to information asymmetry, the sellers of used cars have a lot of information about the used cars, but the buyers of used cars have no information at all about the used cars.

In other words, there is a difference in the amount of information available to buyers and sellers of used cars, and as good quality and poor quality used cars are sold for the same price, sellers of good quality used cars disappear from the used car market, leaving it filled with poor quality used cars.

The same can be said about workers. Generally, a company's job information is presented in a single job posting with monthly salary and benefits. Even if a worker is of a level that would be hired for that job, the salary and benefits when hired will be the same for those hired for the barely available job and those hired with a margin of error. If the people hired for the barely available job are in the bottom 80% and those hired with a margin of error are in the top 20%, the amount of sales will be significantly different due to the 20/80 rule.

The 80/20 rule is the hypothesis that the top 20% of employees contribute to 80% of sales, and therefore the top 20% of employees who generate 80% of sales and the bottom 80% of employees are offered similar salary levels and benefits when they are hired.

Of course, there will be many employees who achieve great results after being hired, and who receive raises and promotions, but if talented employees and less talented employees are offered the same treatment at the time of hiring, it is possible that the same thing will happen as in the market for used car lemons.

Well, I would like to offer my own proposal on what the auction method is for workers' job hunting. First of all, in job hunting, it is of course the workers who have most of the information about the workforce. The workers themselves know best what companies they have worked for, what kind of achievements they have made, their own strengths and weaknesses, and whether they are an excellent worker.

After that, workers submit documents and videos including their work history and self-promotion on a labor auction site, which we will call "Worktion," and undergo screening by companies. When a company wants to hire a certain employee, it is selected by the worker by offering better treatment than other companies.

In other words, the modern method of recruiting is the opposite, with companies posting job postings and having workers choose from them. In workshops, workers submit their job search information and companies set a price for that labor. By posting a job posting, companies can approach people they consider suitable for employment in advance, instead of having unworthy workers apply.

If we are talking about the top 20% of talent, there is a high possibility that companies will compete with each other for them, so the auction will select the company that makes the most attractive proposal for that talent. Of course, it would be a waste to lose the labor force you have selected after going to such lengths after just one interview.

So, for example, I would like to suggest that you conduct a formal interview and then have the person actually work for a month as a trial period. In the case of information asymmetry, the employee has overwhelmingly more information about the person's workforce, and by having the person work for a month, both the employee and the company can confirm whether the person is truly suitable.

Of course, one month is not a very long period. For example, there may be some excellent personnel among the employees who will finally be able to show their true potential after a year. However, a probationary period that is too long can be a burden on the company, and it is expected that the longer the period, the more of a burden it will be for the employees if they are not officially hired.

If you want to eliminate information asymmetry in the used car market, you should set up a trial period for the used car. By doing so, information will be shared between the seller and the buyer of the used car, minimizing losses due to differences in information.

The same is true in the labor market. Auctions allow workers to receive better treatment and companies to avoid interviewing unnecessary candidates, which is thought to reduce the waste of job hunting. Furthermore, by setting up a trial period in addition to interviews, it is possible to aim for a sufficient return for the burden of the auction and to reduce the information gap.

By adopting the auction system in the market for lemons, talented people can be properly evaluated and receive the treatment they deserve. Furthermore, companies can also determine whether or not they have talented people, so it is beneficial for both parties.

This labor auction method can be automated by creating an online website, and it is thought that efficient operation is possible by using manpower from the auction side only when it is needed.

The top 20% of talent generates 80% of sales. By finding a way to properly evaluate the top 20% of talent, talent in the labor market will be allocated efficiently. I would like to propose an auction method for this purpose. The time is ripe. All that remains is to remove preconceived notions of workers and companies. That's all. I hope the labor market will become more sophisticated. Bye.

The formula for determining price begins by considering the economy where there are unsold items! ?

Let's say there is a formula: Sales - Expenses = Profit.

p=price, Ax=sales quantity, x=production quantity, MC=marginal cost

pAx – xMC = π

π＝０

p=(xMC)/(Ax)

We will call this formula the price formula. However, marginal cost MC represents the increase in cost when one more product is produced. Producing 101 products reduces the additional machine cost per product, i.e. fixed cost, by making 101 products rather than 100. If the cost of the machine to produce is $500, then for the 100th product it is 500/100 = $5, and for the 101st product it is 500/101 = $4.95. By adding the variable cost per unit, i.e. the cost of materials, which has the same cost, to this fixed cost, we can calculate the total cost per product.

In economics, if you take the sales volume Ax in the price formula and multiply it by the production volume x and p, and the cost is C, then px-C=π. In this case, the production volume x is in a state where all the production volume is sold, that is, the number of units produced and the number sold are equal, so the production volume Ax = production volume x. This state where everything is sold is called Say's Law in economics. It is the assumption that everything supplied can be sold. Unlike a hundred years ago when production capacity was low, today there is an oversupply, that is, there is enough machinery and equipment to produce more than people want. When x and Ax in the price formula, that is, the production volume and sales volume, are equal, then p=MC, which is the formula for maximizing profits in microeconomics. In other words, the point where the price and marginal cost per unit of a product are equal, which we will call the price and average cost from here on, is the point where the price and cost per unit are equal, and this is the formula for maximizing profits. If variable cost is $5, then the total cost of the 100th unit is $5 + $5 = $10, and the total cost of the 101st unit is $4.95 + $5 = $9.95. So the marginal cost of the 100th unit is $10, and the marginal cost of the 101st unit is $9.95.

Let's rewrite the previous price formula from p=(xMC)/Ax to p=(xAc)/Ax. In other words, we change the marginal cost MC to the average cost Ac.

In this price equation, when sales volume (Ax) increases, price (p) falls. Conversely, when sales volume decreases, price rises. The general equilibrium theory of demand and supply curves learned in microeconomics shows that this is a balanced supply and demand equation in which price rises when demand (sales volume) increases, and price falls when demand decreases.

The relationship between the supply and demand equation and the price equation shows that when demand (sales volume) increases, the price rises in the supply and demand equation, and the price falls in the price equation.

Image training. Let's calculate it here!

Production volume 15 = x

Sales quantity 10 units = Ax

Average cost $5 = Ac

p = (15 x 5)/10 = $7.5. If there are 5 unsold units, the price will be $7.5 based on the average cost of $5. In other words, the total cost is 5 x 15 = $75, so the sales revenue is 7.5 x 10 = $75. Since the sales revenue and total cost are equal, the profit is zero, but the company is still able to break even.

p = (5 x 5)/5 = $5. If there are no unsold items, the price and average cost are the same. Total cost is 5 x 5 = $25, and sales are 5 x 5 = $25, so sales and total cost are equal and profits are zero.

(Q) Now, I would like to set a question. How can we make this pricing formula more practical?

Below, we will explain Fisher's equation of exchange.

Fisher's equation of exchange is MV=PT, also known as the quantity theory of money. M=money supply (money stock), V=velocity of money, P=price, T=real GDP. V=velocity of money is also expressed as V=1/credit multiplier.

From the formula Money Stock = Credit Multiplier x Monetary Base, the money stock is M in Fisher's equation of exchange, and the credit multiplier is expressed as the velocity of money circulation V, so V = 1/credit multiplier, so (Money Stock) x (1/credit multiplier) = MV = Monetary Base = PT = Price Levels x Real GDP = Nominal GDP. Here, comparing V = (1/credit multiplier) with Marshall's k in the Cambridge Quantity Theory of Money, we get V = (1/Marshall's k), and credit multiplier = Marshall's k. Furthermore, monetary base = nominal GDP.

The monetary base is calculated by adding the following four values: money supply, central bank balance sheet, bank balance sheet, and foreign exchange reserves. In Japan, the monetary base is equal to the nominal GDP of Japan, i.e., "Bank of Japan note issuance" + "currency in circulation" + "current account deposits at the Bank of Japan". Conversely, if the monetary base is expanded, the nominal GDP may increase. In terms of causal relationship, it is not clear whether the monetary base or the nominal GDP comes first, but the concept of the monetary base is essential for nominal economic growth. Since the monetary base = prices and real GDP, if you want to suppress inflation, which is high prices, you can see that you can lower the monetary base. In addition, it is the price of money (1/p). In other words, since p is the price, I would like to point out that its inverse is the value of the currency.

(★Assignment★) The following is continued from the ★ mark. Using statistical data, compare the monetary base and nominal GDP figures. The same currency may be used in several countries.

What do rich people study? ? To make money, you need specialized knowledge, not general knowledge! ?

Hello. I'm Watanabe Tenmei from Seito Medical School Clear File. This time, I'm rewriting an article titled "Read materials to give form to ideas rather than study for the sake of studying. by Nada 20231002".

When you think of studying, what comes to your mind? I think many people would say that studying means reading textbooks and solving problems. I myself was the same way until a few years ago, when I thought of studying, I would just read books that interested me.

As I wrote in my previous article before rewriting, I now study materials to put my ideas into shape. Until now, I would have wasted a lot of time trying to gain knowledge that I didn't know if I would ever use.

So-called trivia is knowledge that can become a topic of conversation just by knowing it, but I was wasting my time memorizing a large amount of useless knowledge that I couldn't even talk about. If you don't forget the knowledge you've learned, even just having it as trivia is valuable in the sense that you will use it someday, but I tend to forget knowledge whenever I have the chance to remember it, so my ship of salvation sank along with the Titanic.

In a previous article, I wrote that in addition to reading reference books on subjects you are studying for the first time, if you first take a look at Wikipedia at least once, it will help you understand the overall picture of the subject, and it will be a good preparation that will not be wasted.

In my case, if I study economics, I look for knowledge that can be used to reinforce the price formula I created. Furthermore, in medicine, I read specialized books with an awareness of the autonomic nervous system, aiming to divide illnesses into sympathetic and parasympathetic nervous systems.

I would like to say one thing to people who are about to start studying: studying is based on the law of compound interest. The more you study, the greater your future growth can be expected. For that reason, studying too much or too little is not good. Too much studying can lead to burnout, and too little studying leaves little room for growth.

If you start studying and continue studying for 16 years, you can earn 1 billion yen in 16 years, but will you be able to keep working hard and not give up? Most students study for 12 years, spending 6 years in elementary school, 3 years in junior high school, and 3 years in high school. If you go on to university, it's a 4-year course, so you can see that you will continue studying for a total of 16 years until you graduate straight away.

However, in Japan, most college graduates can earn around 300 million yen in lifetime salary, while only a handful can earn 1 billion yen in lifetime assets. In other words, as long as you stay on track with the content you learn in school, you are guaranteed a lifetime salary of 300 million yen, but it is clear that it is quite difficult to earn more than that.

So how can you earn 1 billion yen in assets? If you want to earn 1 billion yen, the most important thing is to study. Many people may feel resistant to the word "study," so you can just say "learning." This is also lifelong learning, and the content of what you learn is also important.

Being studious is not necessarily rich, but being rich is being studious. If you want to earn as much as the wealthy, you just need to study the same things they study. To become wealthy, you need to think of a new business model and study what is necessary for that business.

Ideally, it would be best if you could do everything related to management by yourself. If you are self-employed and have only one employee, and you can handle everything from sales to accounting and legal affairs by yourself, there would be no problem. However, there is a finite amount of time in a day. There are only 24 hours in a day, so as your business grows, you will need to pay someone to help you.

The knowledge you need to know by then is the knowledge you need to become wealthy. The wealthy often use their knowledge of taxes to save on taxes. Of course, it is common for the wealthy to pay tax accountants to help them save on taxes, but I think it is important for the wealthy themselves to have some knowledge of taxes and laws.

The knowledge I gained at school was to gain culture. Culture is necessary when chatting as a businessman, but I don't think you can make money with culture alone. Culture, for example, knowledge of art and history, is good to have, but even if you don't, you can still make money and live.

At school, students learn general education up until high school, and then move on to specialized courses in their second year of university. In other words, 13 years of school education is spent learning general education, and then it's only in the three years of university that students can finally receive specialized education that will be useful in society. This is why people say that school studies are useless.

So, is general education necessary? Well, general education is the foundation of specialized education. In order to smoothly move on to specialized courses, you need to acquire sufficient knowledge in general education courses. In other words, your time as a student is about building a foundation, and if you study hard, it will become a solid foundation.

On top of that, by mastering specialized education such as that taught at university or graduate school, you can finally say that you are "prepared" to earn money. Earning money is not an easy thing to do, and you will encounter the phenomenon that the rich get richer and the poor get poorer.

People who have made money once can recreate the method of making money, so the better they are at it, the more likely they are to make a lot of money again even if they become penniless. In other words, while studying at school is important for getting an academic background such as graduating from high school or college, learning after entering the workforce is for the purpose of earning money.

If you want to become wealthy quickly, all you have to do is come up with ideas. You can create hit products by coming up with ideas and combinations that no one has ever thought of before. If you get a hit, it's not a dream to make hundreds of millions of yen, and since most people are in a state of mind where they can't think when it comes to coming up with ideas, it's a battle with a few rivals, and you have a good chance of succeeding.

If you want to make money, keep learning throughout your life. As a doctor or programmer, part of your job is to continue learning throughout your life, but if you continue to learn professionally even after you become an adult and use your imagination to come up with ideas, it shouldn't be difficult to earn 1 billion yen.

If you want to make money, make friends with wealthy people and ask them what they usually do. What kind of books do they read and what kind of experiences do they pay for? Your own annual income should be the average of the 10 people around you. By learning and thinking like the wealthy, becoming wealthy is not a dream. That's all. Thank you for listening. Well then.

Communicate to get and give feedback! Don't hesitate to share your ideas with others!

Hello. I am Tenmei Watanabe from Seito Medical School. This time, I will be rewriting the medical school, and the theme is "Let's get feedback."

　Hmm. Feedback. It's a tricky issue. If you have a boss, feedback will come naturally. Your materials aren't good enough. Your sales are dropping, and I wonder why. From compliments to harsh reviews, there are many opportunities to receive feedback when you're in a company.

　For example, let's say you are in charge of developing new products or creating new projects, and you come up with a great idea. Or even worse, let's say you are in sales or human resources, and you come up with a great business model. You want to make 100% of your business profits by spreading the idea widely.　

　What's important here is to get feedback. Suppose you present your idea to your boss in order to get feedback from them. Your boss then presents your idea to your boss's boss as if it were their own. "I, your boss, came up with that idea." Would you get angry at that time? Or would you accept it as a given?

　Even if your boss steals your ideas, I think it's okay if it's just one or two ideas. Your job also includes helping your boss win, and if your boss gets promoted because of your idea, then you've done your job perfectly.

　Rather, you should keep coming up with 10 or 100 ideas so that your boss cannot privatize your ideas as theirs alone.

　This will improve your skills, and your boss will not be able to hide the fact that he has stolen your ideas. If you are an office worker, you can get a higher position by improving your performance with one or two ideas. I think we need to keep thinking desperately to come up with more ideas, rather than sticking to one idea.

　If you keep one great idea to yourself, even if you could potentially mass-produce many more great ideas, your thinking will stop before you get to that point.

　Think hard! If you keep thinking, you will find a breakthrough. Even if you have a better idea, even if your job is to come up with ideas, you probably don't think long and hard to reach that point.

　For example, imagine you are a mathematician trying to solve a difficult, unsolved problem. You will continue to think desperately to find an answer to this unsolved mathematical problem.

　However, no good ideas come to mind no matter how hard you think about it, and you can only think of superficial solutions. You even consider giving up. Will you continue to challenge the math problem in the darkness where you can't see the future?

　I know that many mathematicians have spent their entire lives trying to solve mathematical problems that never found an answer, and I even know that some mathematicians have drawn the jackpot by finding the answer to a problem that had remained unsolved for hundreds of years.

　Even one of these math problems takes a huge amount of time to solve, and many mathematicians have become reclusive after solving it or because they were unable to solve it. If your one great idea was a way to solve this unsolved math problem, would you be willing to take on a new math problem if someone else plagiarized that idea?

　Perhaps an unsolved math problem is an extreme example, but ideally, I think that even a problem that you have finally solved after devoting your life to it should be communicated to your boss in order to get feedback. I think that it is normal for scholars to submit their work to a journal as a paper, but even if it is accepted, if you stop there, there is no next step.

　Of course, if you can solve a famous unsolved problem, you're good to go for the rest of your life, but I think it's more effective to spend the rest of your academic career trying to achieve even greater things than you already have.

　I'm not a mathematician, so this story is irrelevant to me. As I wrote earlier, the mathematician's story is an extreme example. I think that the great ideas we come up with are far easier than the solutions to such unsolved problems.

　Many people may have noticed the business model behind something like a blog, where you buy a used domain cheaply, ask someone else to help you grow the domain, and then sell it for a price higher than the cost of the domain and labor.However, when you first came up with the idea, you probably tried to do it secretly without telling anyone.

Advertisements

REPORT THIS AD

　I recommend getting your idea evaluated by people who are better at business than you and getting feedback. That way, you might come up with a more advanced way of buying and selling domains, or even a more fundamentally new business idea.

　Of course, if you really want to try something out rather than getting feedback, the best feedback you can get is to try it out yourself first. If it works out well, you can get advice from people around you who know the business and can trust you, and it may turn out to be a new idea rather than trying to keep it to yourself.

　I always share my ideas with others. On top of that, I'm always thinking about more advanced ways to do things. It's very appealing to me to make the habit of coming up with new ideas and turn them into a profitable job.

　If you can add a unique element to how you sell domains, it will be something that no one can copy when you talk to others to get feedback, and it may even be a long-term source of funding.

　On the other hand, it is also important to give feedback. If you listen to the other person with empathy, you may hear a lot of secret stories that you want to keep secret. If you give feedback carefully at that time, it is not a dream to become an information platform where information is exchanged around you.

　So, if you add your own ideas to the ideas you hear from others and share them with others, the meeting will produce a meaningful time. Get feedback. If you are a beginner, feedback from your boss is especially important.

　By repeatedly correcting your behavior based on feedback, your skills will improve dramatically. On top of that, you will also be able to give feedback. Don't stick to one idea, but keep coming up with ideas and communicating them to those around you. By becoming the center of attention, you will become a valuable resource for those around you.

　Keep communicating to get feedback. Think hard. That may be where your value lies. That's all. See you later.

Improve your performance without being jealous! ? A brand is something that comes from updating who you want to be! !

Hello. This is Tenmei Watanabe from Seito Medical School. This time, the theme is that trust crumbles all at once. I have no experience with this, so I would like to talk about it with the novice mark of inexperienced.

Trust. Credibility. Brand. There are various ways to express this, but for example, it would be like when a celebrity who was popular on social media encounters a major backlash and loses popularity.

There have been various accusations against him, from relationships with women to power harassment, but with the media at his disposal it would not have been difficult for his brand to be tarnished.

I think there is a price to pay to maintain a brand. For example, if a celebrity is famous, there is no source of controversy if they don't have any scandals.

The same is true of politicians' financial problems; unless they are framed, no one comes forward to expose the scandal.

I'm neither a celebrity nor a politician, so my brand won't be wiped out by a scandal, but my brand itself doesn't really exist at this point, but as someone who uses SNS, There seems to be a possibility that it will catch fire.

Even if a fire breaks out, there are some fierce people who can get out of a pinch by asking back and forth, but there's no smoke without fire, and if you want to become famous, you need to keep your surroundings clean.

If someone becomes a celebrity, they will likely be assigned a personal manager, and it is up to them whether or not they get involved in a scandal.

"Nabe-kun seems to be thinking about where he wants to fight these days, but now that he's reached a turning point with his blog, I think it would be a good idea for him to try his hand at videography. He talked a lot recently about web videos that combined text and video, so I think he might try his hand at YouTube."

I want to continue writing four articles a week, but I also think it would be good to write one 20,000-word article a week and comment on it in video. I also want to expand my YouTube channel to self-produce.

brand. What is a brand? Creating a brand is called branding, and I think a brand can be built by yourself by becoming who you want to be.

I think if you continue to strive towards the person you want to be and continue to produce results, you will create a brand. I feel like a brand is an outcome, so to speak, and it's not something you aim for and build from the beginning.

Of course, whether you self-produce or have a producer, you still have your ideal self. As you continually update your ideal self, if your accomplishments lead to people liking you, the people around you who have become your fans will likely take charge of your brand.

However, I think that people who make a lot of gaffes are less likely to be criticized for their gaffes than serious people who don't make gaffes. It can be said that making gaffes on a regular basis is also a part of self-promotion. Gaffes are not a good thing, though.

"In the end, what do you want to say, Nabe-kun? Beginner Mark should just ride along with his bicycle on the sidewalk. Oh no, I made a gaffe lol."

Well, today has begun. I would like to start the day by writing an article.

A brand may be something that is built up over a long period of time, but a brand may actually be like a slide, where even if you climb up, there are only a few steps, and even if you slide from above, you slide from a not very high place, so perhaps that's just how brands are.

It's not hard to build a brand, and that's why even if it does fall apart, it can be quickly recovered. Many companies that have had problems and lost their brands continue to operate as if nothing happened after a short time has passed.

If you sincerely apologize when you cause a problem, consumers will probably not criticize you too much. Corporate troubleshooters may be advising that if you hold a press conference and sincerely apologize, even though you're crying, the criticism will immediately stop.

A brand is something that comes after a series of results. Improve your performance, gain favorable impressions, and increase your fan base. Even if you are on a roll and have momentum that seems like you can keep delivering results, there may be times when you need to maintain a slow pace and proceed smoothly without causing unnecessary jealousy or envy.

A brand is a strategy, and the important thing is how to imprint a good image in people's minds. In the first place, the word brand comes from the brand that represents the owner of livestock. Perhaps the true role of a brand is to differentiate it from other companies and celebrities.

First, improve your performance so that you don't get jealous. The first step on a brand's long road may start with such a simple strategy. that's all. It's almost time to go to work. Welcome. See you soon.

The die has been cast! ? Deciding where to fight? ? Compete in the real world rather than the aging internet! !

Hello. This is Watanabe Tenmei from Seito Medical School Clear File. This time, I would like to write about the somber theme of "deciding where to fight."

``Nabecchi wants to be the best here and everywhere, but is he really the best?Itchy has the role of Itchy, providing a comfortable space and being there. You have to think it's a good deal. What do you think about that?"

Be the best. If a man has ambition, he wants to be number one wherever he is. Best in school and sports. Or become the best seller in your company. Becoming the Pirate King is about aiming to be the best, but I don't think it's good to be the best at everything.

That's right. If you're a man, you have to decide where you want to fight. There's a saying in the world: "select and concentrate." In order to be the best here, you have to give up being the best in other areas. Of course, if you have the ability to be the best everywhere, that's the best.

However, human ability and time are limited.

``Does Nabecchi want to hit a series of hits or do he want to hit a walk-off home run? Personally, I don't want Nabecchi to be a home run hitter, but to be a hit-producing hitter like Hachiro. What do you think about that, Nabecchi?”

I have been mainly engaged in this space called the Internet. But strangely enough, I feel like the Internet is aging. I'm in my mid-30s, so I think I'm on the border between being young and not so young.

Of course, what if we let go of that fixed idea and focused on the fact that we are still inexperienced? Some people may give you such refreshing comments. that's right. Age doesn't matter. Are you immature or full-fledged? That is more important.

As far as I can see, there are young people in their teens and twenties on the Internet, but they don't seem to be very noticeable. Is it something that is only used by people in their teens and twenties, or is it because people in their 30s and above are more assertive?

Even I, who am not a reader of the Internet, specialize in writing. Rather than reading what others have written, I make my own statements through my blog. But as the Internet has recently aged and I see that it is full of people older than me, I have begun to feel that the Internet is not my main battlefield.

Up until now, I thought it would be okay to upload 3 or 4 articles a week to my blog, but at the moment, I think it would be okay to just upload one long report a week. I started to feel it.

No, that's fine. It's fine to just aim for the invincible 1,000 articles. If I'm told to post three articles a day, and I focus on the Internet, three articles a day may not be an impossible number. Of course, there will be days when I can't write three articles a day, but I think three articles a day is roughly achievable.

However, I have been competing on the Internet for the past 16 years, but recently I have started to think that it would be better to compete in the real world, that is, in everyday life. On the Internet, it is a miserable place where you can only see older people, that is, people in their late 30s or older. I want to make it about fifty-fifty in real life when I interact with older and younger people.

Final Answer. I was part of the Final Answer generation when I was a child, so I don't think teenagers in their teens or twenties would understand if I said Final Answer. Still, I think it's worth talking about, so I want to aim for about 50:50.

Decide where to fight. The big theme this time is, I'm not the Pirate King or Hachiro, but I want to be the best in real life. Real? company? You may be skeptical, but maybe I haven't shown up where I want to fight yet.

If you're a man, go for it! Donphan, charge! If it were the world of Pokemon, what would I want to do? Would I want to collect Pokemon, or would I want to become strong and become the champion? For now, I haven't found a place in real life where I can fight, so I'm going to post about four articles a week for a while.

I think that if I were to talk about myself in real life, like I do in my blog, I would be able to attract a certain amount of interest from people. On top of that, I think it's important to be interested in the other person.

I'm basically a narcissist, or maybe I'm just a person who loves myself. Therefore, I spend a lot of time studying things that interest me, such as mathematics and medicine. When I have a free day, I spend the first and second half of the day doing what I want to do. That is, studying, researching, and blogging.

So, by splitting my day into two parts, a first half and a second half, in other words, doing the things I used to do in one day over the first two days, and using the remaining second two days to gather information about things that my friends are interested in, for example buying women's magazines or buying and reading manga that I find interesting, I can expect my relationships and life to become richer.

After all, the most important thing in the world is human relationships. I've been doing things I'm interested in a lot. So, by spending the whole day doing what I like only in the first half of the day, I felt that I wanted to do things that other people enjoy, that is, to be interested in other people.

Decide where you will fight. I think it would be great if I could talk about the things I write about on my blog in real life. Most of what I write on my blog is basically self-talk, but I think it would be better if I could think of it as a self-introduction and talk about it more openly. On top of that, I think it's important to be interested in what your friends have to say and try to learn more about them.

As I have said many times before, I would like to maintain the same pace of four articles per week for online battles as I have had up until now, but once I know where I will be fighting in real life, I would like to allocate some of that time to fighting in the real world.

My main battlefield was the internet until I was in my mid-thirties, but as I enter middle age, I would like to start fighting in real life. Age doesn't matter. It's much more important whether you're immature or mature. I'll be a full-fledged person. On top of that, the battles on the Internet up until now were just a preliminary battle.

Get real and itchy. That's important. Provides a comfortable space without pushing people around while cooking. That's Itchy's role. Well, the die has been cast. Where will you fight for the rest of your life? that's all. Thank you for your attention. It was Watanabe's own story. See you soon.

Solve cubic equations by prime factorization! ? How to solve 4th and 5th order equations! !

Hello. I'm Tenmei Watanabe from Seito Medical School Clear File. This time I'd like to think about cubic expressions.

Now, suppose we have the expression a^3+103(a^2)+3431a+36593=0. Quickly, this formula is (a+23)(a+37)(a+43)=0, and the answer is a = -23, -37, -43.

Here, a^3 is called the first term, 103(a^2) is the second term, 3431a is the third term, and 36593 is the fourth term.

You can see that the fourth term, 36593, is exactly (-23)x(-37)x(-43) multiplied by (-1). In other words, if you can decompose 36593 into prime factors, you can find the value of a.

Now, let's try dividing this cubic function using long division. The second term is a^2 multiplied by 103. Since this function is a cubic expression, dividing 103 by 3 gives us 34.333..., so we round it down to 34.

Let's take this 34 as a+34 and divide a^3+103(a^2)+3431a+36593. First, let's subtract a^3+103(a^2) by (a+34)x(a^2). a^3 +103(a^2) – a^3 – 34(a^2) = 69(a^2).

The third term, 3431a, and the fourth term, 36593, are the remainder, so adding 69(a^2) gives 69(a^2)+3431a+36593. If we further divide this remainder expression by a+34, we can see that we need to subtract (a+34)x69a=(a^2)+2346a.

The remainder will be 1085a+36593. Furthermore, if we subtract (a+34)x1085 from the remainder, the remainder becomes -297.

The final result is a^3+103(a^2)+3431a+36593=(a+34)(a^2+69a+1085)-297.

Since -297=(-1)x3x3x3x11, this is a combination problem, and we can see that a+34+3=a+37, a+34+(-1)x11=a+23, a+34+3×3=a+43, which can be decomposed into prime factors.

Using this method, you should be able to solve both 4th and 5th order equations. that's all. See you soon.
