Answer 1

Respuesta:

2 + (+9) = 11

2 + (-9) = -7

2 - (+9) = -7

2 - (-9) = 11

3 - (-3) + (-7) = -1

5 + (-7) - (-6) = 4

(-20) + (-10) = -30

-40 + 70 = 30

-50 + 5 = -45

-3 + (-12) = -15

2 + (-2) = 0

-80 + 100 = 20

1 + (-11) = -10

100 + (-50) = 50

-99 + (-1) = -100

50 - 68 = -18

8 - (-8) = 16

-20 - (+10) = -10
