Liu Hui was a great mathematician in Wei and Jin Dynasties and one of the founders of China's classical mathematical theory. He made great contributions to the history of Chinese mathematics. His works mainly include Nine Chapters of Arithmetic Notes and Calculation on the Island, which are the most precious mathematical heritage of China.

Historical influence:

Nine Chapters Arithmetic not only occupies an important position in the history of Chinese mathematics, but also makes an important contribution to the development of world mathematics. Fraction theory and its complete algorithm, proportion and proportion distribution algorithm, area and volume algorithm, and solutions to various application problems are described in detail in the chapters of the book, such as square domain, millet, decay, quotient work and even loss.

The opening method, profit and loss (double hypothesis method), the concept of positive and negative numbers, the solution of linear simultaneous equations and the general formula of integer pythagorean string in Shaoguang, Profit and Loss, Equation and Pythagorean are all outstanding achievements in the history of mathematics in the world. There are Liu Hui's notes and Tang Li's notes in Nine Chapters of Arithmetic Biography.

Introduction to Liu Hui:

Liu Hui (about 225-295), a native of Zouping, Binzhou, Shandong Province, was a great mathematician in Wei and Jin Dynasties and one of the founders of China's classical mathematical theory. Liu Hui has quick thinking and flexible methods. He advocates reasoning and intuition. He was the first person in China who explicitly advocated using logical reasoning to demonstrate mathematical propositions.

Liu Hui's life is a life of hard exploration of mathematics. Although his position is low, his personality is noble. He is not a mediocre man who seeks fame and fame, but a great man who never tires of learning. He left us a valuable fortune. In May, 20021,the International Astronomical Union (IAU) approved the naming of the lunar landforms in China near the landing site of Chang 'e V, and Liu Hui is one of the eight landforms.

His masterpiece Notes on Nine Chapters Arithmetic is the annotation of Nine Chapters Arithmetic. Nine Chapters Arithmetic is one of the oldest mathematical monographs in China, which was written in the Western Han Dynasty. The completion of this book has gone through a historical process. Some of the mathematical problems collected in the book were handed down in the pre-Qin period, and were edited by many people for a long time, and finally sorted out by mathematicians in the Western Han Dynasty.
