56x54Tx54简便计算

a984434583,你好:56*54/55=(55+1)*54/55=55*54/55+1*54/55=54+54/55=54又54/55

原式=[(55+1)(55-1)]/55=[55^2 - 1]/55 = 55 - 1/55 = 54+54/55

53x(46+54)+54

96x54-54x56=(96-56)x54=40x54=2160

56乘以55分之54 =(55+1)x54/55 =55x54/55+1x54/55 =54+54/55 =54又54/55 果我的答案对您有帮助,请点击下面的“采纳答案”按钮,送咱一朵小红花鼓励下吧!

如图

54x(16+27+58-1)=54x[(20-4)+(30-3)+(60-2)-1]=54x[20+30+60-4-3-2-1]=54x100=5400

56*45+56*54+56=56*(45+54+1)=56*100=5600

52x5854+16x54=52*58+54*(16-1)=52*58+54*15=3016+810=3826

237x54-54x37=(237-37)*54=200*54=10800
