International math problems? Mathematics for International Economics and Trade

Plus the 2 yuan taken by the waiter is 29 yuan.

Solve the problem according to the concept of elementary mathematics: adding "take" should mean that it should be equal to adding minus 2, which is actually minus 2

The math is: +2) = -2

So the relation is: 27+(-2) =27-2=25Conclusion: There is no unary argument left.

And your proposition (plus the 2 yuan taken by the waiter is 29 yuan) is wrong. It should be changed to (plus the 2 yuan or 25 yuan taken by the waiter) in elementary school math is very clear, plus what is taken is subtracted from what is taken.

Brother: Don't fool adults into forgetting elementary school knowledge.

This is a narrative of the concept of stealing: "Each tenant paid 10 yuan and returned 1 yuan is 9 yuan per person, three people are 27 yuan, and the 2 yuan taken by the waiter is 29 yuan".

Each person paid 9 yuan, and the three of them had a total of 27 That's right! But the back is wrong.

This 27 includes 25 room rates, and the waiter steals 2 yuan, since this 2 yuan is included in 27, why do you have an extra 2 yuan?

So, the conclusion of 27 + 2 = 29 is meaningless.

The $2 should not be added, it should be subtracted. It should be reduced by 5 yuan for the house price, but in fact, each tenant paid a total of 25 yuan.

This number cannot be counted in this way, and the first 30 rents are a disguise.

Here's the thing.

The house price is 25 yuan, three people share a house, each person takes out 9 yuan, a total of 27 yuan, and the extra two yuan is taken away by the waiter.

1. Don't worry about all, although international economics and ** professional mathematics is compulsory, but mathematics is not a core course. A passing grade is sufficient. The core course of the International Economics and ** major is English, and only good English can you find a job with a professional counterpart.

There's nothing to worry about in math class. If you have a very poor examination style and discipline in college, you can pass by copying it casually.

Finally, I wish you a bright future!

The international trade major is a combination of arts and sciences, mathematics does not have high requirements, basically advanced mathematics, linear algebra, probability theory or something, the average college student has to learn, science students should not be difficult relatively speaking.

The main courses are political economy and micro.

Source Economics, Macroeconomics, International Economics, Econometrics, Introduction to the World Economy, International Finance.

DAO, International**, International** Theory and Practice, Financial Management, International Settlement, Calculus, Linear Algebra, Probability Theory and Mathematical Statistics, Money and Banking, Finance, Accounting, Statistics, Principles of Management. Among them, financial management, international settlement, calculus, linear algebra, probability theory and mathematical statistics, money and banking, public finance, accounting, statistics, and management principles are mathematical, you don't have to worry, all majors in the freshman year are basically the same, as long as you have excellent grades, you can change majors, don't worry too much, as long as you study hard, I wish you a smooth journey.

The mathematics of economics majors is generally economics and economics mathematics series calculus, linear algebra, probability theory and mathematical statistics, statistics, and calculation.

Quantitative Economics. Compared with higher mathematics, it is still simpler As for which school you are asking about the publishing house, it should be that the textbooks used in each school are not exactly the same, you can try the Higher Education Press.

I'm really interested in economics, mathematics is just a foundation, I personally think econometrics is the most useful, and it would be better to dabble in other professional books

Calculus, Linear Algebra, Probability Theory and Mathematical Statistics I graduated from Nanjing Finance and Economics, and I should mainly learn these! Hope it helps!

Collection of previous IMO test questions - Harbin Institute of Technology Press. The book is very detailed, and it also has an extensive collection of solutions to each exercise.

Olympiad Training Question Bank.

1. Economics majors generally need to take mathematics. The following majors without mathematics are provided for reference: Educational Economics and Management, Discipline Teaching (Politics), Master of Accounting, and the specific professional connotation can be searched and understood.

2. It is recommended to go to the graduate admissions website of a school you like, check the [Master's Degree Catalog Catalog], and learn what majors you may be interested in and have a foundation.

3. Selection of majors:

Look at interest, because interest is the lasting motivation for learning.

Second, see if self-study is not difficult, otherwise it will be difficult to go online and useless.

This major is basically a mathematics test. You can choose a simpler one, such as two, and it is much more difficult to count one or three. Or choose an MBA, their math is simpler, the pass rate is also high, and the main part is the interview process.

Interdisciplinary majors such as LL.M. do not require mathematics, but can also be considered?

I translated the questions myself. But you can pay attention to the International Mathematical Olympiad in advance**, register a member or add a QQ group, where everyone has an explanation, discuss with each other, and the translation will be done in a few minutes, and there will be no mistakes. Good luck with that!
