eu agradeço muitoo a quem puder me ajudar..❤️​

Answer 1

Resposta:

a) – 5 – 9 = -14

b) 5 – 7 = -2

c) – 6 – 3 – 4 = -13

d) + 8 + 3 = 11

e) – 3 + 5 + 7 = 9

f) 7 – 15 + 6 – 12 = -14

g) – 3 – 7 – 9 + 20 = 1

h) 1 – 7 + 5 + 3 – 4 = -2

i) (– 6 – 4 + 11) + ( 3 – 8 – 5) = -9

j) (1 – 7 + 4) + (– 2 – 5 + 6) = -3

Espero ter ajudado ^-^
