High number refers to the complicated part of mathematical objects and methods compared with elementary mathematics. Advanced mathematics is the abbreviation of advanced mathematics. It is generally believed that advanced mathematics is a basic subject formed by calculus, algebra, geometry and their intersection. The main contents include: series, limit, calculus, spatial analytic geometry and linear algebra, series, ordinary differential equations.

Generally speaking, science and engineering must be studied, such as physics, chemistry, mathematics, mechanical engineering, electrical and electronic engineering, civil engineering and so on. If you are a liberal arts student, you should also study some subjects, such as economics, accounting and geography, because some subjects involve the application of advanced mathematics.

However, for language and art, there is no need for high numbers. Of course, there is no need to study, such as English major, Japanese major, art film and television, sports, ceramics major, wine tasting, tourism and hotel management, cooking and so on.

Characteristics of high numbers: high abstraction, strict logic and wide application.

1, abstraction and calculation are the most basic and remarkable characteristics of mathematics. Only with a high degree of abstraction and unity can we profoundly reveal its essential laws and make it more widely used.

2. Strict logicality means that in the induction and arrangement of mathematical theories, whether it is concepts and expressions, or judgments and reasoning, we must use the rules of logic and follow the laws of thinking. Therefore, mathematics is also a way of thinking.

3. Widespread application means that the process of learning mathematics is the process of thinking training. The progress of human society is inseparable from the wide application of mathematics. Especially in modern times, the appearance and popularization of electronic computers have broadened the application field of mathematics. Modern mathematics is becoming a powerful driving force for the development of science and technology, and it has also penetrated into the field of social sciences extensively and deeply.
