(a) 1 (B) -5

Explanation:

First SUM (a) :-

If a number (a) is multiplied by a negative number (here, -1) to get a negative number,

Second sum (b) :-

If a number (a) is multiplied by a negative number (here, -1) to get a positive number , then the negative number (-1) should be multiplied by a negative number.

(i.e); (-1) X (5) = -5

                        (-a) = (-1)

    Therefore    (a) = -5
