【简便计算】

简便计算是一种特殊的计算，它运用了运算定律与数字的基本性质，从而使计算简便，使一个很复杂的式子变得很容易计算出得数。

【脱式计算】

即递等式计算，需将一系列的数字逐步计算。在脱式计算中要先算乘、除法，后算加、减法。在乘除法连继计算时中，要按从左往右的顺序依次计算，在四则运算中，加法和减法叫做第一级运算，乘法和除法叫做第二级运算。

【注意事项】

在进行简便运算（ 四则运算）时，应注意运算符号（乘除和加减）和大、中、小括号之间的关连。不要越级运算，以免发生运算错误。

【乘法分配律】

简便计算中最常用的方法是 乘法分配律。乘法分配律指的ax(b+c)=axb+axc其中a,b,c是任意实数。相反的，axb+axc=ax(b+c)叫做乘法分配律的逆运用（也叫提取 公约数），尤其是a与b互为补数时，这种方法更有用。
