35×22脱式计算的简便算法

脱式计算的简便算法 35×22 =35×2×11 =70×11 =770

原式等于 37×(35+65)=3700 ~回答完毕~ ~\(^o^)/~祝学习进步~~~

It's your attitude I don't like。

4.2×(1.25乘以0.8) =4.2x(1.25x0.8) =4.2x1 =4.2

38×29+38 =38×29+38×1=38×(29+1)=38×30=……

脱式计算就是一步一步的算,得出最终结果 。

11×22+0.22×3300+330×4.4 =11×22+22×33+33×44 =11×22+22×33+33×2×22 =(11+33+66)×22 =110×22 =2420 或: 11×22+0.22×3300+330×4.4 =11×22+22×33+33×44 =(11+33)×22+33×44 =44×22+33×44 =44×(22+33) =44×55 =2420 .把小数变成正数,灵活运...

(500-10)✘0.35 =500✘0.35-10✘0.35 =175-3.5 =171.5

88x125 =(11X8)X125 =11X(8X125) =11X1000 =11000 希望对你有帮助,满意请及时采纳, 你的采纳是我回答的动力!

请把题目写清楚
