Jia Xian Jia Xian was an outstanding mathematician in the Northern Song Dynasty in ancient China. The Nine Chapters of the Yellow Emperor's Algorithm Grass (nine volumes) and the Algorithm Collection of Ancient Algorithms (two volumes) (斆xiào, meaning: number guide) have been lost.

His main contribution was to create"Jia Xian Triangle"and multiplication opening method, the multiplication opening method is the positive root method of finding the higher power. At present, the mixed division method in middle school mathematics is similar to this, and the multiplication method is neat and simple than the traditional method, and it is more procedural, so it shows its superiority when opening the higher power, and this method was proposed more than 700 years earlier than the conclusion of the European mathematician Horner.

Qin Jiushao Qin Jiushao (c. 1202-1261), a native of Anyue, Sichuan. He successively served as an official in Hubei, Anhui, Jiangsu, Zhejiang and other places, and was demoted to Meizhou (now Meixian County, Guangdong) around 1261, and died soon after in office. Together with Li Ye, Yang Hui, and Zhu Shijie, he is known as the four masters of mathematics in the Song and Yuan dynasties.

In his early years, he "visited and studied in Taishi, and tasted mathematics from the hermitage gentleman", and wrote the famous "Nine Chapters of the Book of Numbers" in 1247The book consists of 18 volumes and 81 questions, which are divided into nine categories. His most important mathematical achievements --- the total number of large derivations" (the method of solving the congruence group) and the "positive and negative square method"."(Numerical solution of higher-order equations), so that this Song Dynasty arithmetic book occupies a prominent position in the history of mathematics in the medieval world.

Zu Chongzhi Zu Chongzhi (429 500 AD) was an outstanding scientist in the Northern and Southern Dynasties. He was not only a mathematician, but also an astronomer who was well-versed in astronomical calendars, mechanical engineering, and other fields.

Zu Chongzhi's main achievement in mathematics is about the calculation of pi, and he calculated the pi rate as.

Eumedes: Author of Geometry.

The famous German scientist Gaussian Shosun (1777-1855) was born into a poor family. Gauss learned to do arithmetic on his own before he could speak, and one night when he was three years old, he watched his father calculate wages and corrected his mistakes in calculations.

After the long manuscript chain was completed, he became the most prominent astronomer and mathematician of our time. He made some contributions to the electromagnetism of physics, and one of the units of electromagnetism is now named after him. Mathematicians called him "the king of mathematics".
