(1+0.23+0.34)*(0.23+0.34+0.65)-(1+0.23+0.34+0.65)*(0.23+0.34))(1+0.23+0.34)*(0.23+0.34+0.65)-(1+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+0.23+0.34)*(0.23+0.34+0.65)-(1+0.23+0.34+0.65)*(0.23+0.34))

(1+0.23+0.34)*(0.23+0.34+0.65)-(1+0.23+0.34+0.65)*(0.23+0.34))
（1+0.23+0.34）×（0.23+0.34+0.65）－（1+0.23+0.34+0.65）×（0.23+0.34）
这道题目把（1+0.23+0.34）设为A,（0.23+0.34）设为B.
那么原式变成：
A×（B+0.65）－（A+0.65）×B
＝AB+0.65A－AB－0.65B
＝0.65A－0.65B
＝0.65×（A－B）
＝0.65×1
＝0.65
｛因为A＝1+0.23+0.34,B＝0.23+0.34,那么A－B＝1+0.23+0.34-0.23-0.34＝1｝
