Question

Me ajudem a calcular:
a) (3+33:3) x (12:3+1)=

b) 10+(7x7+11):(3x9+3)=

c) 5x(20+2-15) - (7x8-30)=

Answer 1

a) (3+33:3) x (12:3+1) = (3+11) x (4+1) = 14x5 = 70
b) 10+ (7x7+11) : (3x9+3) = 10+ (49+11) : (27+3) = 10+60:30 = 10+20 = 30
c) 5x (20+2-15) - ( 7x8-30) = 5x7- (56-30) = 35-26 = 9

Answer 2

a) (3+33:3) x (12:3+1)= 49
b) 10+(7x7+11):(3x9+3)=393
c) 5x(20+2-15) - (7x8-30)=610
