First, make up the elementary mathematics in senior high school (algebra, solid geometry, trigonometry, plane analytic geometry). Advanced mathematics is completely different from high school mathematics. Understanding doesn't mean you can do the problem, but the exam is a problem, so you must learn to do it.

It takes 1 week to finish the textbooks of all grades in primary schools. Then finish learning junior high school textbooks in half a month. Spend a week sorting out the framework of high school textbooks, and then study according to high mathematics textbooks. The order is to learn a period of high school mathematics first, and then a period of advanced mathematics. Wait until you have finished learning high school math design and plates, and then learn the rest.

Advanced mathematics has its inherent characteristics.

This is a highly abstract, logical and widely used problem. Abstraction and calculation are the most basic and remarkable features of mathematics. Only with a high degree of abstraction and unity can we profoundly reveal its essential laws and make it more widely used. Strict logic means that in the induction and arrangement of mathematical theory, whether it is concept and expression, or judgment and reasoning, we must use the rules of logic and follow the laws of thinking. Therefore, mathematics is also a way of thinking, and the process of learning mathematics is the process of thinking training.
