2. Who was he? Liu Hui was a great Chinese mathematician in the third century. He lived in a time of serious political turbulence in China. The country was split into three kingdoms and Liu Hui was an official of the Kingdom of Wei. After years of war, the Kingdom of Wei came out on top and began to revive literary and scientific classics.

4. As the first person to raise the concept of decimals, Hui also approximated pi and defined a multiple of other concepts including area, power, and equation.Most famous for his annotated text of JiuzhangSuanshu(Nine Chapters on the Mathematical Art), which came into being in the Eastern Han Dynasty.
5. His Contributions Without Hui, math would not have pi >> When he saw China’s value for the ratio between circumference and diameter, he was dissatisfied. In addition to pi, Hui made his own algorithm for pi as well, which was named after him. It was one of his most important contributions to Chinese mathematics.
6. !Bottom-line! Liu Hui was one of the greatest mathematicians of all time. He created pi, calculated area, and a ton of other things. The best part: he did it during a Chinese civil war! He was RIGHT THERE. And I don’t know why people ignore mentioning him when teaching Algebra because without pi, Algebra would just be a bunch of numbers.
