The basic skills of mathematics are also called basic mathematics. Basic mathematics specializes in studying the inherent basic laws of mathematics itself. The knowledge of algebra, geometry, calculus and probability introduced in primary and secondary school textbooks belongs to the basic skills of mathematics. A remarkable feature of basic mathematics is to temporarily put aside the specific content and study the quantitative relationship and spatial form of things in pure form.

Mathematics can be divided into two categories: one is called basic mathematics; One is called applied mathematics.

The first kind of mathematics. It focuses on applying mathematical tools to solve practical problems in work and life. In the process of solving problems, the mathematical tool used is basic mathematics.

The second kind of mathematics. It studies the inherent laws of mathematical structure itself according to the inherent needs of mathematics or its possible future application, rather than seeking the common ground of other disciplines in solving practical problems.
