How bad is math for foreigners?

How bad is math for foreigners? This reminds me of an example I saw before, where a Chinese student and a foreign student in the Department of Architecture discussed a problem together, and then encountered the problem of the angle of a triangle in mathematics. Chinese students say that the three corners of a triangle add up to 180 degrees.

The foreign student said that I didn't believe it, and then he took the protractor and went to measure it, and then found that it was really 180 degrees, so he came back and said to the Chinese student, "Oh my God, you are really a genius." I don't know if this example is fictitious, but foreigners are not good at mathematics, especially British, and there are still a lot of examples to test.

Cameron was once asked in a public interview about 8*9=?As a result, he avoided answering for fear of answering incorrectly. In recent years, the British have been deeply aware of the problem of their basic arithmetic, and the BBC has reported before that the British have caused economic losses of 20 billion pounds to the country every year because of poor arithmetic, including accounting errors and inefficient accounting.

In January 2013, a delegation of UK mathematics teachers came to Ningbo, China, with a huge number of 50 mathematics teachers, all from the top 25 secondary schools in the UK. They came to the school and asked the students some math questions, such as "72 divided by 3 is what is it", and the Chinese students answered 24 in one bite. The British teacher's jaw dropped in shock.

Is this okay? How can you answer it so quickly? You kids actually know how to "multiply tables"??

You know, they divide 72 by 3, and it goes like this: 10x3=30 10x3= 30，4x3=12.

10+10+4=24。After deeply realizing the awesomeness of Chinese arithmetic, in 2014, they invited 60 mathematics teachers from Shanghai to fly to the United Kingdom to share "mathematics teaching experience" with British schools, which was directly responsible for the British Education Secretary at the time.

Seeing the Chinese here, I guess my heart is as dark as mine, right? Hahahahaha.

In the BBC documentary "Chinese New Year", a Beijing taxi driver asked a BBC reporter a question to see the reporter's confused appearance.

The mathematics of the Chinese is like this: when we buy things in the supermarket, we usually have change and give the cashier yuan, and then just give us 5 yuan for change.

However--- the math of foreigners is like this: when we buy something in the supermarket, we usually have change and will give it to the cashier, and then the cashier will return it to you first, and then give change.

There is also a way to use that as a tip.

And this method of finding money is called the Chinese method of finding money in the United States.

1 After reading the probability and statistics published in the United States, I found that the whole book did not mention Bayesian theory, so I went to our university textbook, and on page 25, I also gave 1 line of proof, and came up with 3 questions.

2 Again, these two books do not mention limits and calculus, and the American version is too difficult to mention. Chinese is too shallow, not embarrassed to mention at all, such as the Poisson formula, in fact, you need to push the limit or the law of Lobida, but there is no process at all, and the result is directly written in one step.

And the meaning of saying so much is because it is first suppressed and then promoted.

The difference between the European and American environment and the Chinese environment is that one goes from easy to difficult, and the other goes from difficult to difficult.

In terms of course selection, Europe and the United States actually have a significant score difference when they reach university.

Maybe domestic universities are only exposed to calculus and high math in freshman year. In fact, in the United States, Russian high schools have optional courses, which are abbreviated as AP learning systems, and they study college-difficult mathematics in advance. Even when they started their freshman year, they skipped the calculus of advanced mathematics and spent four years of college in a high-pressure environment, while China played four years in college.

In the United States, college graduation is purgatory.

In China, graduating from university is a step into purgatory from heaven.

I think this has something to do with the gap between Chinese and Western education. And not all foreign mathematics is bad, there are good and bad, otherwise many theorems in the famous higher mathematics are proved by foreigners, such as these mathematicians: Taylor, Newton, Cauchy, etc., are very powerful mathematicians.

In China, Chinese-style education is to memorize everything that can be memorized, and all things must be memorized, for example, when we were in primary school, we had to memorize multiplication formulas, unit conversion, these most basic things, we believe that the most effective way to learn mathematics is to do more problems, exercise problems and calculation ability, especially now primary school students have participated in various Olympiad classes since childhood, mathematics exercises, and their ability to solve mathematical problems is very strong since childhood, so in the eyes of foreigners, Chinese mathematics is particularly good, Because we know a lot of things they don't know, we can figure out questions they can't. In addition, in our country, students have received the same level of mathematics knowledge since childhood, and for some students who can't learn it, they can only register for classes at home.

In the education method for foreigners, the multiplication formula is used to consult, not to remember, and to do the problem is not to make the problem, but to pay attention to the idea. And they are graded according to the individual situation of the students, not like the education method in our country, it is not hard indoctrination, it is not that you can't learn it or you are stupid, I think their education method is more humane.

You can't generalize, just like foreigners think that all Chinese can do kung fu, all Chinese mathematics is good, and then we also think that all foreigners are bad at mathematics. Actually, no, they are like us, there are good and bad maths.

If you search for this question on the Internet, a bunch of web pages will pop up. Take one example after another to prove that foreigners are bad at math, each example is simply a funny joke, and I feel that I have gained insight again.

But is that really the case? I don't think so! Other examples say that foreigners have "bad arithmetic skills, not mathematics". If foreigners really bad at math, those famous foreign mathematicians are not convinced.

From Euclid to the curly-haired Leibniz in history or Newton's predecessors, there are many famous foreign mathematicians!

What we call mathematics can only be regarded as a small part of the larger field of mathematics, and can only be regarded as "arithmetic" at the entry level. Because arithmetic is the most widely used in our daily life, we mean arithmetic is mathematics. In fact, arithmetic is really that simple!

I'm sure there are a lot of people, including myself, who can't understand calculus, can't understand advanced algebra. At the very least, I believe that there are also people who, like me, don't understand what the high school teacher is talking about in class at all. Can't understand what those ghost-like formula letters on black and white are?

I always look at math teachers with the same eye, "How can people be so smart and understand these things, and even more powerful things, if they understand themselves, they can teach others to understand." The math teacher always looked at me with the same look in his eyes: "Classmate, how many times have I said it, you stupid earthling, can you still do it, can you have fun playing?" You come to the office after class!

From those solid geometries to the so-called functions. In fact, I have arranged and combined a few problems correctly, and once thought it was very simple, and I became interested in mathematics again. Do you still think that the power of the desolation has been sealed?

I'm supposed to be a genius, right, but I haven't been discovered? Later, I found out that the reality was very cruel, and there was a lesson in the middle that I didn't listen well because I was excited, and then I turned around and found that I couldn't understand it. Nani, it sounds completely different.

Later, I tried again and still didn't understand, so I dispelled the idea and quietly became a beautiful woman.

Later, in order to talk to Xueba, I also studied it carefully, and I went with confidence, but I found that I didn't understand it at all. It seems that the beautiful man can't save my math nerves.

So don't tell me anything about the world's top seven math problems. Each one of them is a problem for me!

I don't know what kind of brain the person who asked these questions is, and I don't understand how the people who answer them are so smart.

I can't understand at all whether the brain structure of Euler's kind of person who writes so many ** and books is different from ordinary people.

Not to mention inattentive scholars like Galileo, who can study mathematics while being a scientist.

Foreign mathematicians have already gone to see Marx, and they have left countless questions to torment us, so whoever says that foreigners are bad at mathematics is simply saying that it doesn't hurt to have a needle prick with their eyes open.

It's so bad that we can't imagine it, maybe the simplest 1+1 has to think about it for a long time, don't think about such an unthinkable thing, just do our own math well, and you can also go out to show off abroad.

Go to Douglas and buy cosmetics, half price for the second one.

I bought two essences for 100 euros and two bottles of water for 40 euros. When paying, the waiter insists on charging 100 + 100 + 20 + 20

Hehe, I decisively refunded and bought the order twice.

Go to Rothman's supermarket to buy something, buy two get two free for the first one, and buy three get one free for the second one. I bought a lot of things, and the cashier was very clever enough to calculate all the money for me, and then gave me the two cheapest ones for free. Then I started the process of fighting with the waiter, and after discussing for an hour, they didn't change it (that is, I put the unit price of these things together, and then put these unit price things together, they didn't understand), and then decisively returned it to me, and asked me to take it again, one at a time.

There was another time when I bought **, facial cleanser and the like in DM, and bought three brands of ** with a total of 152 pieces (discounted that day) and the young lady at the cashier had a few 36 pieces.

Oh, they are people from small countries, hehehehe, every time I settle accounts, I feel extremely proud, and sure enough, they are still people from our big country.

It's just that the average level of arithmetic among urban people is low. Even so, it cannot change the reality that the academic level of mathematics in China still lags behind that of Europe and the United States. The level of mathematics in the country depends only on the level of mathematicians, not on the masses who can do multiplication of multiple digits.

Mathematicians even determine a country's place in world academia.

Foreigners are bad at math? Don't see how bad, many Chinese look confused about high numbers Oh Koko.

Those who say that foreigners are particularly bad at math, are Chinese good at math? It can only be said partially, don't overturn a ship with one stroke, every country is different for everyone, there are geniuses and idiots who don't work hard. When you are complacent in your heart, maybe someone has already surpassed it, and there is a sky outside the sky.

A classmate of mine, who grew up with me, is better at mathematics than me, immigrated to Malaysia at the beginning of his life, and after a year, he came back for the New Year, and he didn't even know how to use one-yuan equations, why? Because I learned to multiply a single digit by a single digit for another year with a foreigner, I forgot about Chinese mathematics.

Why haven't the Chinese math cows seen how many famous theorem proofs have been made? To put it bluntly, Chinese are simple mathematical proficiency such as daily accounting, and scientific research still can't catch up with foreign countries.

To quote a sentence from the great god of Zhihu: science and technology are driven by elites, not by scumbags. Guys, math is really good.

If foreigners are poor in mathematics, why did the first two hundred years of natural science lead the world, and China's science and technology also lagged behind?

Let me tell you two things.

This is an IGCSE (equivalent to a domestic junior high school) math book for British children, and I have to admit that the Chinese people are quite confident, and everything is the best in our country, right?

Take a look at the table of contents, which deals with three-dimensional vectors, calculus, permutations, imaginary numbers, and even mechanics.

I would like to ask if junior high school students in China can come into contact with these.

For example, I am currently studying at one of the top international high schools in Shanghai, and I went to the United States to participate in a math team competition at MIT, and our team scored 30 points out of 300 points, and most American school teams scored more than 100 points, and the highest was 270, and the group was the only team in the audience without an Asian face.

If you don't like the above, please spray.

They go back to study mathematics because they have the talent or interest in it, and those who are not interested in it learn some basics, otherwise how did those college talents come about?

Although foreigners are poor in mathematics, they are well educated. Students from European and American countries focus on cultivating hobbies, while Chinese students can only "swim" in the sea of questions.

It's true that the general level is low, but it doesn't mean that the top part is low. Some educational atmosphere and intellectual property protection mechanisms in the West have made the upper limit of mathematics proficiency in the West very high, and China needs to improve in this regard.

Math and arithmetic are not the same.

Arithmetic and arithmetic are also different.

What is good in modern China is just counting.

In ancient times, it was arithmetic that was mastered.

There aren't many real math talents.

But the electronic computer was still invented by them, so it can be seen that mathematics is not strong.

I just want you to think about one point, Chinese mathematics is good, foreign mathematics is bad, so why does China only think that it is a Nobel laureate in the field of natural sciences??? Mo Yan belongs to literature) Maybe Chinese students are indeed superior in theoretical knowledge, but they are not as good as others, Chinese mathematics is good, but it is reflected in the test papers and countless test questions, in practice, although it is not to zero points, but it is a failure. That's where we can think deeply.
