(1+0.23+0.34)×（0.23+0.34+0.65）-（1+0.23+0.65）×（0.23+0.34）的巧算
(1+0.23+0.34)×（0.23+0.34+0.65）-（1+0.23+0.65）×（0.23+0.34）的巧算

(1+0.23+0.34)×（0.23+0.34+0.65）-（1+0.23+0.65）×（0.23+0.34）的巧算
(1+0.23+0.34)×（0.23+0.34+0.65）-（1+0.23+0.65）×（0.23+0.34）
=（1+0.57)×(0.65+0.57)-0.57-0.23×0.57-0.65×0.57
=1×(0.65+0.57)+0.57×(0.65+0.57)-0.57-0.23×0.57-0.65×0.57
=0.65+0.57+0.57×0.65+0.57×0.57-0.57-0.23×0.57-0.65×0.57
=0.65+0.57×0.57-0.23×0.57
=0.65+(0.57-0.23)×0.57
=0.65+0.34×0.57
结果自己算吧
