Olá!!

1. Exercício: Simplifique e calcule cada item a seguir:

a. (−2) − (+7) = -2 -7 = -9

b. (+4) − (−4) = +4 +4 = +8

c. (−5) − 0 = -5 -0 = -5

d. (+4) − (−3) = +4 +3 = +7

e. (+8) − 0 = +8 -0 = +8

f. (−4) − (−1) = -4 +1 = -3

g. 0 − (+6) = 0 -6 = -6

h. (−2) − (−1) = -2 +1 = -1

i. 0 − (−2) = 0 +2 = +2

j. (−3) − (+3) = -3 -3 = -6
