Answer 2

Respuesta:

a) +8 – (+8) = 8-8=0

b) –7 – (–2) = -7+2= -5

c) –9 – (–7) = -9+7= -2

d) +3 – (+9) = 3-9= -6

e) +2 – (+2) = 2-2= 0

f) –9 – (–5) = -9+5= -4

g) +6 – (+10) = 6-10= -4

h) –4 – (–11) = -4+11= 7

i) –8 – (+6)= -8+6= -2

j) 9 – (+2) = 9-2= 7

k) –12 – (+8) = -12-8= -20

I) –6 – 0 = -6

m) –3 – (+8) = -3-8= -11

n) –20 – (+12) = -20-12= 32

o) –8 – (+4) = -8-4= -12

p) 12 – (–20) = 12+20= 32
