| It is the basis of the above, the ancient Chinese mathematical calculation known to the world at, and gradually formed from a mathematical system characteristics. Nine Chapters balenciaga magenta giant work on Arithmetic, a book of this system is an important indicator of the formation. Nine Chapters on Arithmetic, a book about in the middle of the first century AD, is a mathematical achievements of the Warring States Period and Qin and Han dynasties of ancient famous Guinness Book count. Set the book title using the application form, a total of income production and life of the 246 math problems and answers. The topics are divided into nine chapters The first chapter, , the main stress is calculatedarea, including the scores of the various calculation methods Chapter II, corn the ratio of talk about various issues, especially with regard to a variety of inter-grain exchange pro-rata method of calculation 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 balenciaga handbags number of patients have a complete solution Chapter VIII of the equation is on the simultaneous solutiongeneral description of group Chapter IX , 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 balenciaga bag 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 balenciaga 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 creation of a cutting circle of the new method of operation. He believes that when the next round with the edge of the infinite regular polygon increases, its perimeter that is increasingly approaching the circumference length, fine cut of indemnity, the indemnity small loss. Cutting and cutting of that can not be cut, and fit with a round having lost everything. 7 from the can see that the idea of Liu Hui has been balenciaga painted fashion collection applied to limit the calculation of pi. Liu Hui application cut-round operation, from the circle next date is hexagonal, while doubling the number of step by step, direct calculation is then to 192 yen in the area of polygon, find the circumference Liu Hui39s work, to derive a precise figure to seven effective pi 3.1415926 lt lt3.1415927. Get this result, which is equivalent to the application of count nine the number of chips on a large number of various operations including prescribing for more than 130 times, the amount of work is not hard to imagine. In order to calculate the square About the rate. Zu Chongzhi data obtained pi, far away in front of the world until after the millennium, the Arab mathematicianal Kashi in the year 1427, the French mathematician-dimensional special leaf Viete AD years 1540- 3, only more accurate data obtained. Obtained dense rate, until the sixteenth century in Europe is to achieve. | ||
