Answer 1

Explicación paso a paso:

$+ ( + 9) - ( + 6) = 3 \\ - ( + 7) + ( - 3) = - 10 \\ + ( - 5) - ( - 5) = 0 \\ - ( - 2) - ( - 8) = 10 \\ + ( - 4 + 9) - ( + 6) = - 1 \\ - ( - 10) + ( + 3 - 15) = - 2 \\ - ( - 3 + 11 - 8 + 6) = 12 \\ + ( - 1 + 4) - ( + 17 - 6) = - 20 \\ - ( - 8 + 3) + ( - 5 - 19) = - 13$
