六年级数学简便运算典型例题

六年级数学简便运算典型例题

简便运算典型例题简便运算是一般不需要用笔列竖式,而直接用口算就能够算出得数。

它的类型很多,下面列举了二十几个例题,且附有练习,希望认真完成。

运算定律★例1:1.24+0.78+8.76★例2:156+44+135=〔1.24+8.76〕+0.78 =〔156+44〕+135 =10+0.78 =200+135 =10.78 =335【解题关键和提示】运用加法的交换律与结合律,因为1.24与8.76结合起来,和正好是整数10。

有时正好是整百、整千。

练习 :1、0.21+12.3+0.79+7.7 6、653+131+2.4+1312、3.51+2.74+6.49+7.26 7、74+91+73+1983、271+98+29 8、1592+3698+408+3024、142+29+271+3585、96.8+1.29+3.2+3.71★例3:933-157-43★ 例4:65-3.28-6.72=933-〔157+43〕 =65-〔3.28+6.72〕=933-200 =65-10=733 =55【解题关键和提示】根据减法去括号的性质,从一个数里连续减去几个数,可以减去这几个数的和。

此题157与43的和正好是200。

练习:1、896-246-554 6、9.5-2.36-5.642、2021-169-531-209 7、42-1381353、5600-564-436-129-371 8、15.9-11.7-8.34、98-12.6-57.4 9、98.6-74735、500-56.4-43.6-36.9-63.1 10、8.85-3.38-4.62+1.15★例5:4821-998 ★例6:653-102= 4821-〔1000-2〕=653-100-2=4821-1000+2 =553-2=3823 =551【解题关键和提示】此题中的减数998接近1000,我们就把它变成1000-2,根据减法去括号性质,原式=4821-1000+2,这样就可以口算出来了,计算熟练后,998变成1000-2这一步可省略。
