小学四年级简便计算题大全

网上有关“小学四年级简便计算题大全”话题很是火热,小编也是针对小学四年级简便计算题大全寻找了一些与之相关的一些信息进行分析,如果能碰巧解决你现在面临的问题,希望能够帮助到您。

一定要把括号外的数分别乘括号里的两个数,再把积相加或相减。

(8+40)×25 125×(8+80) 48×(5+100) 24×(2+10) 75×(1000— 2) 15×(40— 8)

例如:

(1)2.64×51.9+264×0.481

=264×0.519+264×0.481

=264×(0.519+0.481)

=264×1

=264

(2)9.16×1.53-0.053×91.6

=9.16×1.53-0.53×9.16

=9.16×(1.53-0.53)

=9.16×1

=9.16

简便计算

简便计算中最常用的方法是乘法分配律。乘法分配律指的是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。

也有时用到了加法结合律,比如a+b+c,b和c互为补数,就可以把b和c结合起来,再与a相乘。如将上式中的+变为x,运用乘法结合律也可简便计算。
