The development history of mathematics can be roughly divided into four periods. The first period is the formation period of mathematics, and the second period is the period when mathematics remains unchanged. Its research results include Lee's constant formula, Fahrenheit theorem, Su's cone and so on.

First stage

The first period: the formation period of mathematics (ancient times-the sixth century BC), which is the period when human beings established the most basic mathematical concepts. Since counting, human beings have gradually established the concept of natural numbers, simple calculation methods, and recognized the most basic and simplest geometric forms. Arithmetic and geometry are not separated.

stage Ⅱ

The second period: elementary mathematics period and constant mathematics period (6th century BC-AD17th century), the basic and simplest achievements in this period constitute the main content of middle school mathematics, which lasted for about two thousand years. This period gradually formed the main branches of elementary mathematics: arithmetic, geometry and algebra.

The third stage

The third period: the period of variable mathematics (1early 7th century to1end of 9th century). Variable mathematics came into being in17th century, and has gone through two decisive and significant steps: the first step is the generation of analytic geometry; The second step is the creation of calculus.

The fourth stage

The fourth period: the modern mathematics period (beginning at the end of19th century), the beginning of the modern stage of mathematics development, which is characterized by profound changes in all foundations-algebra, geometry and analysis.
