在宋元以前,中国数学是遥遥领先于世界的.同学们都知道祖冲之吧(429—500),他所求出的8位有效数字圆周率就是一项顶了不起的数学成就.其计算精度纪录保持了近千年,直至被阿拉伯数学家卡西(1380—1429)打破.更值得称赞的是,魏晋时期的数学家刘徽(225—295)全面证明了《九章算术》(成书于1世纪,汇集了中国古人的数学研究)中的公式和解法,奠定了中国古代数学的理论基础.在《九章算术》里,专设有方程一章,给出了有关二元一次方程组的8个问题.其解法理论与现在的“加减消元法”基本一致.
Before the Song and Yuan dynasties, Chinese mathematics was far ahead of the world, and all the students knew Zu Chong (429-500), and the eight significant figures that he had found were a remarkable achievement in mathematics. Nearly a thousand years, until it was broken by the Arab mathematician Casey (1380-1429) More commendably, the Wei and Jin Dynasties mathematician Liu Hui (225-295) fully proved “nine chapters of arithmetic” (into the first century, Which brings together the formula and solution method in mathematics research of Chinese ancients and lays the theoretical foundation of ancient Chinese mathematics.In the Chapter Nine Arithmetic, a chapter of equations is specially set forth, and eight equations of binary linear equations Problem.The theory of solution is basically consistent with the current “addition and subtraction elimination method”.
