简便计算题乘除法

乘法的简便运算技巧:

增补简便运算。对数字进行补增或差分。目的是形成后几位为0的整数,如40、 567900等。

位数差分。将数字差分为各个位数,如56789=50000+6000+700+80+9。利用乘法运算性质,分别相乘。这种方法运算简单,但需要注意的是若乘号前后数字均为复杂的多位数,该方法虽然简化的乘法运算,但却增加了加法运算难度。

除法的简便运算技巧

将除法转化为分数,对分子、分母同时提取公约数,减少多位数运算难度。

差分分子,形成多个由分母倍数组成的多项式加法运算。例如 768/8=(800+8-40)/8.

当分子小于分母时,也可以考虑将分子、分母上下倒置,差分新分子,计算结果。但须注意倒置后的结果是原题结果的倒数。
