The author of Nine Chapters Arithmetic is no longer here. It is generally believed that it has gradually become the final version after several generations of supplement and modification. Zhang Cang and Geng Shouchang in the Western Han Dynasty had been supplemented and sorted out, and they were generally finalized at that time. The last book was in the early years of the Eastern Han Dynasty at the latest, and most of them were Notes to Nine Chapters written by Wei Yuan, Jing Yuan and Liu Hui in the Three Kingdoms Period (263).

It is the first mathematical monograph in ancient China, and the most important of the ten classic works of calculation, which was formed around the first century A.D.. The book is very rich in content and summarizes the mathematical achievements in the Warring States, Qin and Han Dynasties.

At the same time, Nine Chapters Arithmetic has its unique achievements in mathematics. It not only mentioned the problem of score at the earliest, but also recorded the problem of surplus and deficiency at the earliest. Zhang Equation also expounded the negative number and its addition and subtraction algorithm for the first time in the history of world mathematics. It is a comprehensive historical work and the most concise and effective applied mathematics in the world at that time. Its appearance marks the formation of a complete system of ancient mathematics in China.

The nine chapters on arithmetic are very rich in content. In the form of problem sets, the book contains 246 applied questions related to production and life practice, in which each question has questions (questions), answers (answers) and skills (steps to solve problems, but there is no proof), some have one skill for one question, and some have many skills for many questions.

According to their properties and solutions, these problems belong to,, decline (Cui) points, Shao Guang, Shang Hong, continuous loss, profit, loss, equation and Pythagorean respectively. * * * Nine chapters are as follows. The original edition has illustrations, and this edition only leaves the text. Nine Chapters Arithmetic contains 246 math problems, which are divided into nine chapters.
