Salut!
3. Dacă a = 24+15-28:4, b = 100-23x3-22:2, c = 2x2x2:4, calculează cât mai simplu:
a = 24+15-28:4 = 32
a = 24+15-7
a = 39-7
a = 32
b = 100-23x3-22:2 = 20
b = 100-69-11
b = 31-11
b = 20
c = 2x2x2:4 = 2
c = 4x2:4
c = 8:4
c = 2
a) a+b-c+a+c-b+a = 96
32+20-2+32+2-20+32 = 96
b) b+c+a+c-b-a+c = 6
20+2+32+2-20-32+2 = 6
c) c+b+a+c-b-a+c = 6
2+20+32+2-20-32+2 = 6
Spor la teme!
