8乘43减860乘0.09

8乘43减860乘0.09
11·8×43-860×0·09
=5·9×2×43-86×0·9
=86×﹙5·9-0·9﹚
=86×5
=430

11·8×43-860×0·09
=5·9×2×43-86×0·9
=86×﹙5·9-0·9﹚
=86×5
=430

430

=11.8*43-43*20*0.09=11.8*43-43*1.8=43*(11.8-1.8)=430

11.8*43-860*0.09
=43*(11.8-1.8)
=43*10
=430

11.8*43-860*0.09
=11.8-20*0.09(两边同时除43)
=11.8-1.8
=10
