Find the sum :
(a) (– 7) + (– 9) + 4 + 16
(b) (37) + (– 2) + (– 65) + (– 8)

Solution:

We use the concepts of positive and negative integers to find the values of the given expressions.

(a) (– 7) + (– 9) + 4 + 16 = (- 7 - 9) + (4 + 16) = - 16 + 20 = 4
(b) (37) + (– 2) + (– 65) + (– 8) = (+37) + (- 75) = 37 - 75 = - 38
