乘法算没有分先后顺序所以原式
=125*5*8*8*5
=1000*5*40
=1000*200
=200000
=125*5*8*8*5
=1000*5*40
=1000*200
=200000

125×5×64×5
＝125×8×（5×4）×（5×2)
＝1000×20×10
＝200000
＝125×8×（5×4）×（5×2)
＝1000×20×10
＝200000

125x5x64x5
=25x5x5x4x4x4x5
=25x4x(25x4)x(5x4)
=100x100x20
=200000
=25x5x5x4x4x4x5
=25x4x(25x4)x(5x4)
=100x100x20
=200000
