Answer 2

Oie, Td Bom?!

>>> Resolvendo as expressões.

a) (- 3) - (+ 4) = - 3 - 4 = - 7

b) (- 7) - (- 3) = - 7 + 3 = - 4

c) (+ 9) - (+ 2) = 7

d) (- 1) - (+ 6) = - 1 - 6 = - 7

e) (+ 4) - (- 1) = 4 + 1 = 5

f) (- 6) - (+ 2) = - 6 - 2 = - 8

g) (+ 9) - (+ 6) = 3

h) (- 3) - (- 3) = 0

i) (+ 2) - (- 6) = 2 + 6 = 8

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

k) (- 1) - (+ 3) = - 1 - 3 = - 4

l) (+ 2) - (- 6) = 2 + 6 = 8

m) (- 10) - (- 2) = - 10 + 2 = - 8

n) (+ 6) - (- 5) = 6 + 5 = 11
