125x32-125x24

原式 =125x8x4-125x8x3 =1000x4-1000x3 =4000-3000 =1000 或者: 125x(32-24) =125x8 =1000

原式=125(32-24)=1258=1000

125x32x0.25解:=125x(4x8)x0.25=125x8x(4x0.25)=1000x1=1000祝学习进步.

125x32-125x24=125*(32-24)=125*8=1000

式子=125x(32-24)=125x8=1000 再看看别人怎么说的.

=125*8*4-125*8*3=4000-3000=1000

125x(32-24)

=125*(32-24)=125*8=1000

125乘以32减125乘24 =125*(32-24) =125*8 =1000
