﹝1+0.12+0.23﹞*﹝0.12+0.23+0.34﹞—﹝1+0.12+0.23+0.34﹞*﹝0.12+0.23﹞

﹝1+0.12+0.23﹞*﹝0.12+0.23+0.34﹞—﹝1+0.12+0.23+0.34﹞*﹝0.12+0.23﹞
=﹝1+0.12+0.23﹞*﹝0.12+0.23﹞+﹝1+0.12+0.23﹞*﹝0.34﹞—﹝1+0.12+0.23﹞*﹝0.12+0.23﹞-﹝0.34﹞*﹝0.12+0.23﹞
=﹝1+0.12+0.23﹞*﹝0.34﹞-﹝0.34﹞*﹝0.12+0.23﹞
=0.34*(1+0.12+0.23-0.12-0.23)
=0.34*1
=0.34
