分析:(1)把96拆成95+1,再根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(2)括號(hào)內(nèi)連續(xù)減去
,等于減去
的和,然后再進(jìn)一步計(jì)算即可;
(3)先計(jì)算除法,再計(jì)算乘法,然后約分計(jì)算即可;
(4)本題乍一看能運(yùn)用乘法分配律進(jìn)行簡(jiǎn)算,仔細(xì)一分析,應(yīng)先計(jì)算除法和乘法,最后計(jì)算減法;
(5)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(6)先計(jì)算括號(hào)內(nèi)的減法,再計(jì)算除法即可.
點(diǎn)評(píng):能簡(jiǎn)便計(jì)算的,要靈活運(yùn)用運(yùn)算定律,然后再進(jìn)一步進(jìn)行計(jì)算,不能簡(jiǎn)便計(jì)算的,要按照運(yùn)算順序進(jìn)行計(jì)算.
