一九章算术是我国最古老的算經之一,現傅本九章算术是經魏刘徽(263年)和唐李淳風等人(656年,至今恰为1300年)注釋过的注釋本,它比較有系統地記載了我国古代数学的各个方面,本文的目的就是要尝試对其第8章方程中关於代数学方面,特别是关於“方程”解法方面的成就加以叙述。方程章第1問:“今有上禾三秉中禾二秉下禾一秉实三十九斗,上禾二秉中禾三秉下禾一秉实三十四斗,上禾一秉中禾二秉下禾三秉
The ninth chapter is one of the oldest arithmetics in China. Fu Benjiu’s arithmetic is annotated by Wei Liuhui (263) and Tang Lifeng (1966 and now 1300). It is more systematic. All aspects of ancient Chinese mathematics are documented. The purpose of this paper is to try to describe the achievements in algebra, especially the “equation” solution, in Chapter 8 equations. The first chapter of the equation: Q: “There is a thirty-nine bucket in the upper floor, three in the upper floor, two in the upper floor, two in the upper floor, two in the upper floor, three in the upper floor, three in the lower floor, and one in the third.禾2 Bingxia 禾 San Bing
