25*(-0.125)*(-4)*(-4/5)*(-8)*5/4 简便算法

25*(-0.125)*(-4)*(-4/5)*(-8)*5/4 简便算法
=[25*(-4)]*[(-0.125*(-8)]*[(-4/5)*(5/4)]
=-100*1*(-1)
=100

原式=25×(-4)×(-1/8)×(-8)×(-4/5)×(5/4)
=-100×1×(-1)
=100

25*(-0.125)*(-4)*(-4/5)*(-8)*5/4
=(25*-4)*(-0.125*-8)*(-4/5*5/4)
=-100*1*(-1)
=100

25*(-0.125)*(-4)*(-4/5)*(-8)*5/4
=25*0.125*4*(4/5)*8*5/4
=(25*4)*(0.125*8)*{(4/5)*(5/4)}
=100*1*1
=100
