(1+0.23+0.33)*(0.23+0.33+0.43)-(1+0.23+0.33+0.43)*(0.23+0.33
3个回答
把1+0.23+0.33 和 0.23+0.33 看做一个整体,假设分别为a、b那题目可以如下
a*b+a*0.43-a*b-0.43*b
=0.43(a-b)
=0.43*1
=0.43

如何算0.13 0.23 0.33 0.43 .0.93=?
(1).1,0,-1,(),-33(2).87,67,45,23,((3).3,-2,0,-3,-4,((4).0,-2
(1+0.23+0.34)*(0.23+0.34+0.45)-(1+0.23+0.34+0.45)*(0.23+0.34
巧算(1+0.23+0.34)*(0.23+0.34+0.65)-(1+0.23+0.34+0.65)*(0.23+0.
(1+0.23+0.34)x(0.23+0.34+0.65)-(1+0.23+0.34+0.65)x(0.23+0.
简便计算:(1+0.23+0.34)*(0.23+0.34+0.65)-(1+0.23+0.34+0.65)*(0.23
(1+0.23+0.34)×(0.23+0.34+0.65)-(1+0.23+0.34+0.65)×(0.23+0.34
(1+0.12+0.23)×(0.12+0.23+0.34)-(1+0.12+0.23+0.34)×(0.12+0.23
(1+0.23+0.34)x(0.23+0.34+0.65)-(1+0.23+0.34+0.65)x(0.23+0.34
(1+0.12+0.23)×(0.12+0.23+0.34)-(1+0.12+0.23+0.34)×(0.12+0.23
