專題:運(yùn)算順序及法則,運(yùn)算定律及簡(jiǎn)算
分析:(1)先算除法,再算減法;
(2)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(3)根據(jù)減法的性質(zhì)進(jìn)行簡(jiǎn)算;
(4)根據(jù)乘法分配律進(jìn)行簡(jiǎn)算;
(5)先算乘法,再算加法,最后算除法;
(6)先算減法,再算加法,最后算乘法.
解答:
解:(1)916-4832÷16
=916-302
=614;
(2)826×99+826
=826×(99+1)
=826×100
=82600;
(3)16.32-(6.32+4.8)
=16.32-6.32-4.8
=10-4.8
=5.2;
