The mathematician known as China Euclid is 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. He has made great contributions to the history of Chinese mathematics, and his masterpieces "Nine Chapters of Arithmetic Notes" and "Arithmetic on the Island" are the most precious mathematical heritages of China.
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.
The influence of the work:
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 field, 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.
