Siddhartha's time was a prosperous time for Indian mathematics, whose mathematics content was mainly arithmetic and algebra, and was obviously influenced by Greek mathematics, and some famous mathematicians appeared, such as Aliyepodo, Brahmaguta, Raft Tuomona and Pashgaro. The earliest Indian mathematician known today is Ayabata, who has only one astronomical mathematics book, Ayabata Calendar, which has been handed down from generation to generation. The most prominent feature of this book lies in the improvement of Greek trigonometry and the solution of an indefinite equation. Aryabhata's habit today is to make a half chord correspond to half of the arc that the whole chord subtends. At the same time, he measured the arc in radius, which is actually the beginning of arc measurement.

Brahmagupta's two astronomical works, Brahmagupta's Revision System and Kende Cartier, both contain a lot of mathematical contents, and their algebraic achievements are very valuable. He regarded 0 as a number, which was accepted by Raft Tomona and Schridde Haller in the 9th century. Brahmagupta has a clear understanding of negative numbers and puts forward the multiplication and division rules of positive and negative numbers ~
