解题思路:(1)利用乘法交换律简算;
(2)(3)利用乘法分配律简算;
(4)按照从左到右的顺序计算;
(5)利用减法的性质简算;
(6)把88拆成11×8,利用乘法结合律简算.
(1)25×71×4
=25×4×71
=100×71
=7100;
(2)48×27+73×48
=48×(27+73)
=48×100
=4800;
(3)102×35
=100×35+2×35
=3500+70
=3570;
(4)33+7.83+6.7
=40.83+6.7
=47.53;
(5)53.76-5.71-4.29
=53.76-(5.71+4.29)
=53.76-10
=43.76;
(6)88×125
=11×(8×125)
=11×1000
=11000.
