Answer 1

Ley de signos:

$( + )( + ) = + \\ ( - )( - ) = + \\ ( + )( - ) = - \\ ( - )( + ) = -$

Solución:

1)

$( - 17) + ( + 4) = - 17 + 4 = - 13$

2)

$( - 12) + (0) = - 12 + 0 = - 12$

3)

$(0) + ( + 3) + (- 4) = 0 + 3 - 4 = - 1$

4)

$( - 1) + ( + 6) + ( - 2) = - 1 + 6 - 2 = + 3$

5)

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