诗歌体古题是我国古代民间数学流传的一种主要形式,在四世纪至十六世纪,诗歌体的数学古题比较盛行.诗歌体数学古题,读起来朗朗顺口,妙趣横生,便于记意.介绍一道关于一个不定方程的诗歌体数学古题,摘自《孙子算经》,原文是:“今有物不知其数,三三数之剩二,五五数之剩三,七七数之剩二,问君其物几何?”这个问题颇有猜谜的趣味,解法也很巧妙,明朝大数学家程大位在《算法统宗》里也用诗歌给出解法:“三人同行七十稀,五树梅花廿一枝,七子团圆正半月,除 The poetic body ancient poem is a kind of main form that the ancient folk mathematics spreads in China. From the fourth century to the 16th century, the poetic body is more prevalent in mathematics. Introduction to an indefinite equation poetic math problem, excerpted from ”The Book of the Sun Tzu“, the original is: ”I do not know the number of this thing now, the remaining number three three, five five number of the remaining three or seven seven The remaining two, what is its geometry? “This is quite a quiz puzzle, the solution is also very clever, the Ming dynasty mathematician Cheng Da-bit in the” algorithm Uehara “also use poetry to give solution: ” Three Seven seventy peers, five trees plum twenty-one, seven round reunion is a month, except
