c) 2 x (7 + 1) - 32 : (7 + 9) =
d) 9 x (3 + 7) - 30 : (9 + 6) =
e) 4x(6 + 1) - 10: (1 + 9) =
​

Answer 1

Olá!

a) 2 x (7 + 1) - 32 : (7 + 9)

2 x 8 - 32 : 16

16 - 32 : 16

16 - 2

= 14

b) 9 x (3 + 7) - 30 : (9 + 6)

9 x 10 - 30 : 15

90 - 30 : 15

90 - 2

= 88

c) 4 x (6 + 1) - 10 : (1 + 9)

4 x 7 - 10 : 10

28 - 10 : 10

28 - 1

= 27
