(1+0.33+0.44)x(0.33+0.44.+0.55)-(1+0.33+0.44+0.55)x(0.33+0.44)
=(1+0.33+0.44)x(0.33+0.44.)+(1+0.33+0.44)*0.55-(1+0.33+0.44)x(0.33+0.44)-0.55x(0.33+0.44)
=(1+0.33+0.44)x(0.33+0.44.)-(1+0.33+0.44)x(0.33+0.44)+(1+0.33+0.44)*0.55-0.55x(0.33+0.44)
=(1+0.33+0.44-0.33-0.44)*0.55
=0.55
=(1+0.33+0.44)x(0.33+0.44.)+(1+0.33+0.44)*0.55-(1+0.33+0.44)x(0.33+0.44)-0.55x(0.33+0.44)
=(1+0.33+0.44)x(0.33+0.44.)-(1+0.33+0.44)x(0.33+0.44)+(1+0.33+0.44)*0.55-0.55x(0.33+0.44)
=(1+0.33+0.44-0.33-0.44)*0.55
=0.55
