分析:(1)先算除法,再按照從左向右的順序進(jìn)行計(jì)算;
(2)根據(jù)乘法交換律和結(jié)合律進(jìn)行計(jì)算;
(3)根據(jù)乘法分配律進(jìn)行計(jì)算;
(4)根據(jù)連減的性質(zhì)進(jìn)行計(jì)算;
(5)根據(jù)乘法分配律進(jìn)行計(jì)算;
(6)根據(jù)連減的性質(zhì)進(jìn)行計(jì)算.
解答:解:
(1)75+360÷20+48,
=75+18+48,
=93+48,
=141;
(2)125×39×8×2,
=(125×8)×(39×2),
=1000×78,
=78000;
(3)37×28+28×63,
=(37+63)×28,
=100×28,
=2800;
(4)9.26-1.36-0.26-3.64,
=(9.26-0.26)-(1.36+3.64),
=9-5,
=4;
(5)58×99+58,
=58×(99+1),
=58×100,
=5800;
(6)5.76-(3.76+1.8),
=5.76-3.76-1.8,
=2-1.8,
=0.2.
點(diǎn)評:此題主要考查整數(shù)數(shù)的四則混合運(yùn)算的運(yùn)算順序和應(yīng)用運(yùn)算定律進(jìn)行簡便計(jì)算.
