Question

Stiind ca a=166+179,b=632-465 si c=923-745 calculează : a+b= a+c= b+c= a-b = a-c= c-b= a+b-c= c+b-a= a+c-b=

Answer 1

a=345 b=167 c=148
a+b=345+167=512
a+c=345+148=493
b+c=167+148=315
a-b=345-167=178
a-c=345-148=197
c-b=148-167=-19
a+b-c=345+167-148=364
c+b-a=148+167-345=-30
a+c+b=345+148-167=326
