Answer 1

Explicación paso a paso:

a) +5 + (+5) = 5 + 5 = 10

b) –4 + (–4) = -4 - 4 = -8

c) +9 + (–15) = 9 - 15 = -6

d) –20 + (+3) = -20 + 3 = -17

e) –5 + (+2) = -5 + 2 = -3

f) +8 – (+8) = 8 - 8 = 0

g) –9 – (–7) = -9 + 7 = -2

h) –8 – (+6) = -8 - 6 = -14

i) 12 – (–20) = 12 + 20 = 32

j) +2 – (+2) = 2 - 2 = 0

da mejor respuesta porfa.
