(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)*(0.12+0.23)-0.34*(0.12+0.23)
=(1+0.12+0.23)*[(0.12+0.23+0.34)-(0.12+0.23)]-0.34*(0.12+0.23)
=(1+0.12+0.23)*0.34-0.34*(0.12+0.23)
=[(1+0.12+0.23)--(0.12+0.23)]*0.34
=1*0.34
=0.34
(1+0.12+0.23)*(0.12+0.23+0.34)-(1+0.12+0.23+0.34)*(0.12+0.23)
=(1+0.35)*(0.35+0.34)-(0.35+1.34)(0.35)
=0.35²+1.34*0.35+0.34-0.35²-1.34*0.35
=0.34
(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)
