1. Classified memory method is to classify the memory materials according to their nature, characteristics and internal relations, which helps students to remember a lot of knowledge.

2. The method of memorizing songs and rhymes is to compile the mathematical knowledge to be memorized into songs, rhymes or jingles for easy memorization.

3. Conventional memory method.

4. List memory method is to list some easily confused memory materials into tables to achieve the purpose of memory.

5. Key memory method With the growth of age, more and more mathematical knowledge is learned. Students' comprehensive memory is a waste of time and the memory effect is poor.

Mathematics is a science that studies quantitative relations and spatial forms in the real world. It is produced and developed in the long-term practical activities of human beings. Originated from counting and measurement, with the development of productivity, there is an increasing demand for quantitative research on natural phenomena; At the same time, due to the development of mathematics itself, it has a high degree of abstraction, strict logic and wide applicability.

Now it can be roughly divided into basic mathematics (also called pure mathematics) and applied mathematics. The former includes mathematical logic, number theory, algebra, geometry, topology, function theory, functional analysis and differential equations. The latter includes probability theory, mathematical statistics, computational mathematics, operational research and combinatorial mathematics.
