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. The content of the final version circulated today was formed before the Eastern Han Dynasty.
Brief introduction of Liu Hui
Liu Hui (about 225-295), a native of Zouping, Binzhou City, Shandong Province, was witty and flexible, advocating both 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.
Liu Hui's achievements in mathematics can be roughly divided into two aspects: one is to sort out China's ancient mathematical system and lay its theoretical foundation, which is embodied in Nine Chapters of Arithmetic Notes. It has actually formed a relatively complete theoretical system, number system theory, area and volume theory. Second, on the basis of inheritance, put forward your own ideas. This aspect is mainly reflected in the following representative innovations: Moher's square cover theory, new equation technology, gravity difference technology and so on.
