preciso monta essas contas ​

Answer 1

Resposta:

12 - 4 x 2 + 1 = 12 - 8 + 1 = 4 + 1 = 5

9 + 5 x 3 - 4 = 9 + 15 - 4 = 24 - 4 = 20

8 + 6 : 2 - 3 = 8 + 3 - 3 = 11 - 3 = 8

27 : 3 x 4 - 12 = 9 x 4 - 12 = 36 - 12 = 24

40 : 10 + 4 x 6 - 8 = 4 + 24 - 8 = 28 - 8 = 20

35 : 7 + 20 : 5 - 2 x 4 = 5 + 4 - 8 = 9 - 8 = 1

3 + 5 x 2 - 4 : 2 = 3 + 15 - 2 = 18 - 2 = 16
