Answer 2

( + 5 ) - ( + 3 ) = + 2
( - 5 ) - ( + 1 ) = - 6
( - 20 ) - ( - 30 ) = + 10
( + 8 ) - ( - 8 ) = + 16
( + 15 ) - ( + 10 ) = + 5
( - 28 ) - ( + 12 ) = - 40
( - 14 ) - ( - 20 ) = + 6
( - 19 ) - ( - 19 ) = 0
( + 8 ) - ( - 3 ) = + 11
( - 24 ) - ( - 10 ) = - 14
( - 10 ) - ( + 12 ) = - 22
( - 15 ) - ( + 10 ) = - 25
( + 14 ) - ( - 5 ) = + 19
( - 38 ) - ( - 12 ) = - 26
( - 6 ) - ( + 6 ) = - 12
( + 17 ) - ( - 7 ) = + 24

Espero ter ajudado !!!
