(2)(20+25)×8,運(yùn)用乘法分配律進(jìn)行簡算;
(3)125×88,把88分解為8×11,再運(yùn)用乘法結(jié)合律進(jìn)行簡算;
(4)456-169-156-31,運(yùn)用減法的運(yùn)算性質(zhì)進(jìn)行簡算;
(5)136×101-136,運(yùn)用乘法分配律進(jìn)行簡算;
(6)18×36+6×36-36×4,運(yùn)用乘法分配律進(jìn)行簡算.
解答:解:(1)37+125+63+175,
=(37+63)+(125+175),
=100+300,
=400;
(2)(20+25)×8,
=20×8+25×8,
=160+200,
=360;
(3)125×88,
=125×(8×11),
=(125×8)×11,
=1000×11,
=11000;
(4)456-169-156-31,
=(456-156)-(169+31),
=300-200,
=100;
(5)136×101-136,
=136×(101-1),
=136×100,
=13600;
(6)18×36+6×36-36×4,
=(18+6-4)×36,
=20×36,
=720;
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.
