解:(1)58×99+58,
=58×(99+1),
=58×100,
=5800;
(2)101×88,
=100×88+1×88,
=8800+88,
=8888;
(3)125×32×25,
=(125×8)×(4×25),
=1000×100,
=100000;
(4)117+48+52+83,
=(117+83)+(48+52),
=200+100,
=300;
(5)88×125,
=11×(8×125),
=11×1000,
=11000;
(6)336-156-144,
=336-(156+144),
=336-300,
=36.
分析:(1)58×99+58,運(yùn)用乘法分配律進(jìn)行簡算;
(2)101×88,運(yùn)用乘法分配律進(jìn)行簡算;
(3)125×32×25,把32分解為8×4,然后運(yùn)用乘法結(jié)合律進(jìn)行簡算;
(4)117+48+52+83,運(yùn)用加法交換律和結(jié)合律進(jìn)行簡算;
(5)88×125,把88分解為11×8,然后運(yùn)用乘法結(jié)合律進(jìn)行簡算;
(6)336-156-144,運(yùn)用減法的運(yùn)算性質(zhì)進(jìn)行簡算.
點(diǎn)評:此題考查的目的是理解掌握加法、乘法的運(yùn)算定律和減法的運(yùn)算性質(zhì),并且能夠靈活運(yùn)用這些運(yùn)算定律和運(yùn)算性質(zhì)進(jìn)行簡便計算.
