13、不变。这叫做加法交换律。 用字母表示：a+b=b+a三个数相加，先把前两个数相加，或者先把后两个数相加，和不变。用字母表示：(a+b)+c= a +( b+c)3、乘法交换律：4、乘法结合律：两个因数交换位置，积不变。用字母表示：axb-bxa三个数相乘，先把前两个数相乘，或者先把后两个数相乘，积不变。用字母表示 ：(axb)xc= ax(bxc)5、乘法分配律：两个数的和与一个数相乘， 可以先把它们与这个数分别相乘， 再相加。用字母表示：(a+b)xc= axc+bxcax( b+c) =axb+axc拓展：(a-b)xc= axc-bxcax( b-c) =axb-axc6、减法的性质：一个数连续减去两个数，可以减去这两个减数的和。用字母
