“0”是一个十分美妙的数字,它像初升的太阳,十五的月亮,更像一枚鲜果,一颗明珠。它的作用无比,不可思议;它独立存在又介于正数和负数之间;它表示一个数,但这个数却表示什么也没有,然而没有它就无法表示所有的数。 看来如此简单的“0”,在我国古代数学史的长河中,经历了十分艰难而漫长的发展过程。大 “0” is a very wonderful number, like the rising sun, fifteen moon, more like a fruit, a pearl. Its function is incomprehensible and incredible; it exists independently and between positive and negative numbers; it represents a number, but it means nothing, but without it it can not represent all numbers. It seems that such a simple “0” has undergone a very difficult and long process of development in the long history of ancient Chinese mathematics. Big
