Answer 2

Explicação:

$( + 5 ) + ( + 4 ) - ( + 3 )\\+ 5 + 4 - 3 \\+ 9 - 3 \\+ 6$

$( - 8 ) - ( + 6 ) + ( + 3 ) - ( + 2 )\\-8 - 6 + 3 - 2 \\-14+ 3 - 2 \\-11 - 2 \\-13$

$( + 15 ) + ( + 3 ) - ( + 7 )\\+ 15 + 3 - 7 \\+ 18 - 7 \\+11$

$+ 9 - 4 + 3\\5 + 3\\+8$

$- 10 + 6 - 8 + 2\\- 4 - 8 + 2 \\-12 + 2 \\-10$

$+ 10 - 8 + 6 - 4 + 2\\+ 2 + 6 - 4 + 2 \\8 - 4 + 2 \\4 + 2 \\+6$
