10.4-9.6*0.35怎样巧算10.4-9.6*0.35怎样巧算10.4-9.6*0.35怎样巧算10.4-9.6*0.35=10.4-(10-0.4)*0.35=10.4-3.5+0.14=6.
10.4-9.6*0.35 怎样巧算
10.4-9.6*0.35 怎样巧算
10.4-9.6*0.35 怎样巧算
10.4-9.6*0.35
=10.4-(10-0.4)*0.35
=10.4-3.5+0.14
=6.9+0.14=7.04
10.4-9.6*0.35=10+0.4-(10-0.4)*(0.4-0.05)=10+0.4-(4-0.5-0.16+0.2)=6+0.7+0.16=6.86
10.4-9.6×0.35
= (10+0.4)-(10-0.4)×0.35
=10*(1-0.35)+0.4*(1+0.35)
=6.5+0.54
=7.04
(10+0.4)-(10-0.4)*0.35=10*(1-.035)+0.4*1.35.。。。。。接下的自已算啦。。。
