1238–1298), courtesy name Qianguang (谦光), was a Chinese mathematician from Qiantang (modern Hangzhou), Zhejiang province during the late Song Dynasty (960-1279 AD). Yang worked on magic squares, magic circles and the binomial theorem, and is best known for his contribution of presenting 'Yang Hui's Triangle'.

This triangle was the same as Pascal's Triangle, discovered by Yang's predecessor Jia Xian (贾宪). Yang was also a contemporary to the other famous mathematician Qin Jiushao.

Written work

The earliest extant Chinese illustration of 'Pascal's Triangle' is from Yang's book Xiangjie Jiuzhang Suanfa (详解九章算法)[1] of 1261 AD, in which Yang acknowledged that his method of finding square roots and cubic roots using "Yang Hui's Triangle" was invented by mathematician Jia Xian [2] who expounded it around 1100 AD, about 500 years before Pascal.
