125×96×80带有竖式的简便计算

125×80×96这样算,具体见图:

125×8×3=1000×3=3000

95×125=11875 竖式: 简便用脱式: 95×125 =96×125-125 =12×8×125-125 =12000-125 =11875

列式计算为 320×80=25600 所以原式的计算结果为25600.

120乘96简便计算 =120x(100-4) =120x100-120x4 =12000-480 =11520

32×125 =4×(8×125) =4×1000 =4000,

1.01×0.99竖式简便计算 =(1+0.01)x(1-0.01) =1x1-0.01x0.01 =1-0.0001 =0.9999

简便计算: 125×6 =(100+25)×6 =100×6+25×6 =600+150 =750 竖式见图:
