（0.12+0.23+0.34）*（0.23+0.34+0.45）-（0.12+0.23+0.34+0.45）*（032+034）简便计算
（0.12+0.23+0.34）*（0.23+0.34+0.45）-（0.12+0.23+0.34+0.45）*（032+034）
简便计算

（0.12+0.23+0.34）*（0.23+0.34+0.45）-（0.12+0.23+0.34+0.45）*（032+034）简便计算
最后是（0.23+0.34）的话：
假设A=0.12+0.23+0.34,B=0.23+0.34
原式=A×（B+0.45）-（A+0.45）×B,
=AB+0.45A-AB-0.45B,
=0.45×（A-B）；
把A=0.12+0.23+0.34,与B=0.23+0.34代入上式得：
0.45×（0.12+0.23+0.34-0.23-0.34）,
=0.45×0.12,
=0.054
