c) -14-8-3
d) -36+27
e) -18-17+27
f) +18-25+13
g) +27+14+16​

Answer 1

Resposta:

+5-7+8=6

+19+12+6=37

-14-8-3=-25

-36+27=-9

+18-25+13=6

27+14+16=57

Answer 2

a) 5 - 7 + 8 = 13 - 7 = 6

b) 19 + 12 + 6 = 37

c) - 14 - 8 - 3 = - 14 + 8 + 3 = - 22 + 3 = - 25

d) - 36 + 27 = - 36 - 27 = - 9

e) - 18 - 17 + 27 = - 35 + 27 = - 8

f) 18 - 25 + 13 = 31 - 25 = 6

g) 27 + 14 + 16 = 57
