Question

daca a =10 lei , b =50 lei si c=100 lei calculati
(axb)+c
a+b+c
c+c-a
c+c-(5xa)
c+b-(2xa)
c-c+(10xa)

Answer 1

(axb)+c=
10x50+100=
500+100=600

a+b+c=10+50+100=160

c+c-a=100+100-10=190

c+c-(5xa)=
100+100-5x10=
100+100-50=150

c+b-2xa=
100+50-2x10=
100+50-20=150

c-c+10xa=
100-100+10x10=100

Answer 2

(axb)+c=(10 x50)+100=500+100=600

a+b+c=10+50+100=160

c+c-a=100+100-10=190

c+c-(5 x a)=100+100-(5x10)=200-50=150

c+b-(2 x a)= 100+50-(2 x 10)=150-20=130

c-c+(10 x a)= 100-100+(10 x 10)=100
