分析:(1)569+68+132+31,意義加法交換律和結(jié)合律進(jìn)行簡(jiǎn)算;
(2)125×88,將原式轉(zhuǎn)化為:125×8×11,然后運(yùn)用乘法結(jié)合律進(jìn)行簡(jiǎn)算;
(3)2300-165-35,根據(jù)減法的運(yùn)算性質(zhì)進(jìn)行簡(jiǎn)算;
(4)125×(8+4),運(yùn)用乘法分配律進(jìn)行簡(jiǎn)算;
(5)3200÷25÷4,根據(jù)除法的運(yùn)算性質(zhì)進(jìn)行簡(jiǎn)算;
(6)156×l0l-156,運(yùn)用乘法分配律進(jìn)行簡(jiǎn)算.
解答:解:(1)569+68+132+31,
=(569+31)+(68+132),
=600+200,
=800;
(2)125×88,
=(125×8)×11,
=1000×11,
=11000;
(3)2300-165-35,
=2300-(165+35),
=2300-200,
=2100;
(4)125×(8+4),
=125×8+125×4,
=1000+500,
=1500;
(5)3200÷25÷4,
=3200÷(25×4),
=3200÷100,
=32;
(6)156×l0l-156,
=156×(101-1),
=156×100,
=15600.
點(diǎn)評(píng):此題考查的目的是理解掌握加法、乘法的運(yùn)算定律、減法、除法的運(yùn)算性質(zhì),并且能夠運(yùn)用這些運(yùn)算定律和運(yùn)算性質(zhì)進(jìn)行簡(jiǎn)便計(jì)算.
