Chapter III bad points , say the distribution of goods or by grade assessed the proportion of tax issues Chapter IV, less wide , stresses open square, the cube is calculated
Chapter V business credit , say the size of a variety of shapes is calculated
Chapter VI, are lost, according to the population how to speak, and prices are high or low, long distance and other factors to calculate tax and distributed around theissues such as the calculation method
Chapter VII of the lack of profit , that is the assumption that the method used to solve the problem of a class is as follows This year there are people to buy a total of complex, each of eight people the money a surplus of three the money, each Seven people money less than four money, Q the number of geometric price? 6 such problems, in the Nine Chapters on the number of patients have a complete solution
Chapter VIII of the equation is on the simultaneous solutiongeneral description of group
Chapter IX tiffany , mainly the application of the Pythagorean Theorem and right triangle similar to the ratio between a variety of measurement and calculation of high, deep, broad, far problem.
Jiuzhang arithmetic, not only to prepare a more complete structure, forming a style of mathematics has its own system, and the mathematical level of the advanced in the ranks of the world, some of which achievement is far ahead in the world. Such as insufficient surplus technique similar to modern determinant method , which side in Europe to the Middle Ages to the double-try to form Until the sixteenth century in Europe when the parties reached a similar simultaneous equations of the general solution equation has been introduced in chapter the concept of negative and has produce and use the positive and negative addition and subtraction rules, and India to the seventh century, the Europe to the sixteenth century, the only have a clearer concept of the negative.
To Jiuzhang arithmetic of mathematics in China as the representative system, characterized by community based solution for the main purpose of the practical problems in order to count as the main financing tool, the value of a decimal system of notation system operator, its content, including arithmetic, algebra, geometry, and so on. The mathematical system in its own course of development, gradually moving towards its peak, has not changed the long-sheng of the situation, and forged many of the fruit. The most outstanding achievements are
The ancient world, the most accurate pi. Wei Jing-three million four years 263 years, the famous mathematician Liu Hui in the Nine Chapters on Arithmetic as a note, the tiffany
