Ancient mathematics in China reached its peak in Song and Yuan Dynasties, and many outstanding mathematicians appeared. Among them, Qin, Yang Hui and Zhu Shijie are the most famous and have the most outstanding achievements, and they are called the four great mathematicians in Song and Yuan Dynasties.

Qin, Song and Yuan Dynasties were four great mathematicians.

Main achievements: 1947 successfully compiled the mathematical work "Nine Chapters of Several Books".

Qin (1208-1268) was a famous mathematician in the Southern Song Dynasty. He used to be the magistrate of Qiongzhou, Si Nongcheng, etc. Later, he was demoted for some reason, and finally worked in Meizhou, where he died.

Qin's father, Qin, is a scholar who works as a doctor and secretary in the imperial court. Qin was very clever since he was a child. 123 1 successfully passed the examination of Jinshi, and served as a county magistrate, judge and other positions. He has his own research and views on mathematics all his life. He studied mathematics in his spare time and finally made his own achievements in mathematics.

1274, Qin successfully completed the book "Nine Chapters of Shu Shu", in which the techniques of "seeking a big derivative and seeking a skill" and "three oblique quadrature" are of great significance to the world.

Ye Li

Major achievements: celestial magic

Ye Li (1 192? 1279), a mathematician in Jin and Yuan Dynasties, was once the governor (now Yuxian County, Henan Province) and lived in seclusion in Fenglongshan for ten thousand years, imparting knowledge. He not only has achievements in mathematics, but also has his own opinions in literature. Many poems are excellent and circulated in the market.

Ye Li's most outstanding achievement in mathematics is talent, which is a way to solve equations by setting unknowns. This achievement has successfully influenced the mathematics field in China and even the world.

Yang Hui

Main achievements: incremental method, vertical and horizontal diagram and superposition technology have been improved.

Yang Hui is from Qiantang, which is now from Hangzhou, Zhejiang. He was an outstanding mathematician in the Southern Song Dynasty. Yang Hui used to be a local official in the Southern Song Dynasty, and he was a relatively clean official. He has his own research on mathematics. In the process of becoming an official, he has been summarizing folk multiplication and division methods and agile algorithms. Stacking? Wait a minute.

Yang Hui left a large number of works, including five mathematical masterpieces, such as Detailed Explanation of Nine Chapters' Algorithms and Daily Algorithms, with a total volume of 2 1.

Zhu Shijie

Major achievements: creation? Quaternary technology? 、 ? Stacking method? With what? Recruitment?

Zhu Shijie (1249-13 14), a mathematician and educator in Yuan Dynasty, was born in Yanshan (now Beijing). He devoted his life to mathematics and education. Zhu Shijie kept digging on the basis of Monty, and finally developed it successfully? Quaternary technology? The so-called quaternion method is a method of listing high-order quartic polynomial equations and successfully eliminating them to get the final solution. Besides? Stacking method? And then what? Recruitment? He created them all, which is of great significance to mathematics.

Zhu Shijie is not only a mathematician, but also a math educator. He has been studying nine chapters of arithmetic, and he is proficient in many other algorithms. He is well-deserved one of the four great mathematicians in Song and Yuan Dynasties.
