(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)+0.34x(1+0.12+0.23)-(1+0.12+0.23)×(0.12+0.23)-0.34x(0.12+0.23)
=0.34x(1+0.12+0.23)-0.34x(0.12+0.23)
=0.34x1+0.34x(0.12+0.23)-0.34x(0.12+0.23)
=0.34
=(1+0.12+0.23)×(0.12+0.23)+0.34x(1+0.12+0.23)-(1+0.12+0.23)×(0.12+0.23)-0.34x(0.12+0.23)
=0.34x(1+0.12+0.23)-0.34x(0.12+0.23)
=0.34x1+0.34x(0.12+0.23)-0.34x(0.12+0.23)
=0.34

（1+0.12+0.23）X(0.12+0.23+0.34) - (1+0.12+0.23+0.34)X(0.12+0.23)
=（0.12+0.23+0.34）+（0.12+0.23）×(0.12+0.23+0.34) - (0.12+0.23)-(0.12+0.23+0.34)×（0.12+0.23）
=(0.12+0.23+0.34) - (0.12+0.23)
=0.34
=（0.12+0.23+0.34）+（0.12+0.23）×(0.12+0.23+0.34) - (0.12+0.23)-(0.12+0.23+0.34)×（0.12+0.23）
=(0.12+0.23+0.34) - (0.12+0.23)
=0.34
