Answer 1

Oie, tudo bom?

Jogo de sinais em anexo.

O sinal de mais (+) não precisa aparecer.

a) 3 + (- 2) = 3 - 2 = 1

b) (- 4) + 10 = - 4 + 10 = 6

c) 5 - (- 3) = 5 + 3 = 8

d) 11 - 11 = 0

e) 2 . 6 = 12

f) 15 ÷ 3 = 5

g) 4 . (- 2) = - (4 . 2) = - 8

h) 8 ÷ (- 4) = - (8 ÷ 4) = - 2

i) (- 5) . (- 2) = 5 . 2 = 10

j) (- 20) ÷ (- 4) = 20 ÷ 4 = 5

k) (- 4) . 7 = - (4 . 7) = - 28

l) (- 25) ÷ 5 = - (25 ÷ 5) = - 5
