What's the difference between one and three in postgraduate mathematics? Whether the teaching materials are the same. Why is it also a management major? Some schools require math three, while others require math. 1. Math 1 and Math 3 include: high numbers, linear algebra, probability theory and mathematical statistics, but the specific details are not the same. There are many contents in Math 1, but there are few contents in Math 3, such as high-number multiple integral and probability hypothesis test, but the probability part is a little more difficult than Math 1.

2. The textbooks are slightly different. For example, the textbook of Mathematics III is Wu Chuansheng's version of economic mathematics, which is essentially the same. Some topics in science and engineering books are repetitive (I have read them all).

It is normal that different schools have different requirements for different types of majors. For example, academic and professional computers can take Math I and Math II, which depends on the orientation and regulations of the school for this major.
