Answer 1

Explicação:

calcule as diferenças:

a) (-5)-(-6)=> -5+6=>1

b)(+7)-(+2)=7 - 2=>5

c)(-9)-(7)=> - 9 - 7=> - 16

d)(+7)-(-5)=> +7 + 5=> +12

e)(+7)-(+4)=> +7 - 4=> +3

f)(-5)-(+2)=> - 5 - 2 => - 7

g)(-6)-(-7)=> - 6 + 7=> - 1

h)(-2)-(+8)=> - 2 - 8=> - 10

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

j)(+9)-(-7)=> + 9 + 7=>+16

l)(-5)-(+6)=> -5 - 6=> - 11

m)(+5)-(-4)=> +5 + 4=>+9

n)(-5)-(-2)=> - 5 + 2=> - 3

o)(+9)-(-5)=> +9 + 5=> +14

p)(-4)-(+4)=> - 4 - 4 => - 8

q)(+6)-(-4)=> +6 + 4=> + 10
