Answer 2

Resposta:

Explicação passo-a-passo:

A)

= (+12)+(-5)-(-3)

= 12 - 5 + 3

= 7+3

= 10

b)

= (-42)-(+15)+(-33)

= - 42 - 15 - 33

= - 57 - 33

= - 90

c)

= (-35)+(+41)+(-21)

= - 35 + 41 - 21

= 6 - 21

= - 15

d)

= (+45)-(-21)

= 45 + 21

= 66

e)

= (-19)-(51)+(-22)+(+36)

= - 19 - 51 - 22 + 36

= - 70 + 14

= - 56

f)

=(-17)-(+35)-(-23)+(-41)

= - 17 - 35 + 23 - 41

= - 17 - 12 - 41

= - 29 - 41

= - 70
