先来看一道中国古代的数学题:假如有山田三亩,场地六亩,共折输粮实田四亩七分:又有山田五亩,场地三亩,共折实田五亩五分,问每亩山田折实田多少,每亩场地折实田多少?本题出自清朝数学家梅文鼎于1672年完成的的著作《方程论》.《方程论》全书共分为正名、极数、致用、刊误、方程御杂法、测量六卷.首卷《正名》讨论了“方程”一词的含义并按系数符号的排列情况,对线性
Let us first look at a topic of ancient Chinese mathematics: If there are three acres of Yamada, six acre of land, a total of four-fold grain discount farmland seven points: another five acres of Yamada, three acres of site, Ask how much per acre field Tian Tian, how much acre Tian per acre field? This question from the Qing mathematician Mei Wending completed in 1672, “equation.” “The equation” the book is divided into the name, the number of poles, The first volume of “Zhengming” discussed the meaning of the term “equation” and according to the arrangement of coefficient symbols, the linearity
