(1+0.23+0.34)×(0.23+0.34+0.65)-(1+0.23+0.34+0.65)×(0.23+0.34)
=(0.23+0.34+0.65)+(0.23+0.34)×(0.23+0.34+0.65)-(0.23+0.34)-(0.23+0.34+0.65)×(0.23+0.34)
=0.23+0.34+0.65-0.23-0.34
=0.65
=(0.23+0.34+0.65)+(0.23+0.34)×(0.23+0.34+0.65)-(0.23+0.34)-(0.23+0.34+0.65)×(0.23+0.34)
=0.23+0.34+0.65-0.23-0.34
=0.65
