Question

Cat fac a+b+c daca:
a=30:6+90x2
b=12+3:3
c=66:33-11

Answer 1

a = 30 : 6 + 90 x 2
a = 5 + 180
a = 185

b = 12 + 3 : 3
b = 12 + 1
b = 13

c = 66 : 33 - 11
c = 2 - 11
c = - 9

185 + 13 - 9 = 189

Sau

30 : 6 + 90 x 2 + 12 + 3 : 3 + 66 : 33 - 11 =
= 5 + 180 + 12 + 1 + 2 - 11
= 185 + 12 + 1 + 2 - 11
= 197 +1 +2 - 11
= 198 + 2 - 11
= 200 - 11
= 189

Daca te - am ajutat da - mi coroana !

Answer 2

a = 30 : 6 + 90 x 2
a = 5 + 180
a = 185

b = 12 + 3 : 3
b = 12 + 1
b = 13

c = 66 : 33 - 11
c = 2 - 11
c = - 9

a + b + c = 185 +13 - 9 = 198 - 9=189
