问题描述：
0.125×0.32—0.25×0.16 简算
答
原式=0.125X2X0.16-0.25X0.16=0，太简单了吧
答
0.125*0.32-0.25*0.16=0.125*2*0.16-0.125*2*0.16=0
*为乘号
答
0.125*0.32—0.25*0.16
=0.125*0.16*2-0.25*0.16
=0.125*2*0.16-0.25*0.16
=0.25*0.16-0.25*0.16=0
答
0.125×0.32—0.25×0.16=0.125*0.32-0.125*2*0.16=0.125*0.32-0.125*0.32=0
答
0.125×0.32-0.25×0.16
=0.125×0.32-0.125×2×0.16
=0.125×0.32-0.125×(2×0.16)
=0.125×0.32-0.125×0.32
=0
答
0.125×0.32-0.25×0.16
=0.125×0.32-0.125×2×0.16
=0.125×0.32-0.125×(2×0.16)
=0.125×0.32-0.125×0.32
=0.125×（0.32-0.32）
=0.125×0
=0
