h) 15 + (8 x 8 + 26) : (3 x 9 + 3) =

Answer 1

Resposta:

a) 10 + 2 x 9 =  10+18=28

b) 46 - 3 x 4 = 46-12=34

c) 30 - 50 : 5 + 1 = 30-10+1=21

d) 128 : 2 : 2 : 8 = 16

e) 15 + 3 - 4 x 4 + 5 = 18-12+5=11

f) 6 x (3 + 6) = 6*9=54

g) 200 - (7 x 9 + 3) = 200-(63+3)=200-66=134

h) 15 + (8 x 8 + 26) : (3 x 9 + 3) =15+90/30= 18
