分析:(1)运用乘法交换律与结合律简算;’
(2)(4)(5)(7)运用乘法分配律简算;
(3)把101看作100+1,运用乘法分配律简算;
(6)把32看作8×4,运用乘法结合律简算;
(8)运用减法的性质简算.
解答:解:(1)25×14×4
=25×4×14
=100×14
=1400;
(2)72×17+17×28
=(72+28)×17
=100×17
=1700;
(3)67×101
=67×(100+1)
=67×100+67
=6700+67
=6767;
(4)57×29+57
=57×(29+1)
=57×30
=1710;
(5)32×89+10×32+32
=32×(89+10+1)
=32×100
=3200;
(6)125×32×25
=125×8×4×25
=(125×8)×(4×25)
=1000×100
=100000;
(7)136×82-82×36
=(136-36)×82
=100×82
=8200;
(8)6236-482-1518
=6236-(482+1518)
=6236-2000
=4236.
