Answer 1

Explicación paso a paso:

$- 1 - 3 - ( - 9) + ( - 5) \\ - 4 + 9 - 5 \\ 5 - 5 = 0$

$17 + ( - 8) + ( - 8) \\ 17 - 8 - 8 \\ 9 - 8 = 1$

$- 2 + ( - 3) + 4 - ( - 3) - 5 \\ - 2 - 3 + 4 + 3 - 5 \\ - 5 + 4 + 3 - 5 \\ - 1 + 3 - 5 \\ 2 - 5 = - 3$

$- 5 - 15 + 4 - ( - 3) - 5 \\ - 20 + 4 + 3 - 5 \\ - 16 + 3 - 5 \\ - 13 - 5 = - 18$

$- 5 - 15 + 4 + 15 \\ - 20 + 4 + 15 \\ - 16 + 15 = - 1$

$2 - 3 + ( - 5) + ( - 3) \\ - 1 - 5 - 3 \\ - 6 - 3 = - 9$
