在数论中,整数与整除问题占有十分重要的地位,在各级各类的数学竞赛中经常出现这一类的问题.下面,我们将有关的必要基础知识整理如下,供大家学习时参考. 一、整数 正整数、0、负整数统称整数.整数具有以下三个性质: (1)1是最小的正整数. (2)整数的个数是无限的,既没有最小的整数,也没有最大的整数. (3)两个整数的和、差、积仍是整数,但两个整数的商(除数不为0)不一定是整数.
In number theory, the problem of integers and integers occupies a very important position. This type of problem often occurs in various types of mathematical competitions. Below, we will arrange the necessary basic knowledge as follows for reference when learning. , integer positive integers, 0, negative integers are collectively referred to as integers. Integers have the following three properties: (1) 1 is the smallest positive integer. (2) The number of integers is infinite, neither the smallest integer nor the largest Integers. (3) The sum, difference, and product of two integers are still integers, but the quotient of two integers (divisor is not zero) is not necessarily an integer.
