Question

Fie a si b doua numere naturale, unde :a=(73x9-318-777:3)+796-63x10 ; 6-5:[4-3:(2-2:b)]=1 Calculeaza diferenta dintre produsul si suma celor doua numere

Answer 1

a= (657-318-259)+796-630= 80+796-630=876-630=246

5:[4-3:(2-2:b)]=6-1
4-3:(2-2:b)=5:5
4-3:(2-2:b)=1
3:(2-2:b)=4-1
3: (2-2:b) =3
2-2:b=3:3
2-2:b=1
2:b=2-1
2:b=1
b=2x1
b=2

(246x2)- (246+2) = 492-248=244
