Find the sum:

(a) (-7) + (-9) + 4 + 16

(b) (37) + (-2) + (-65) + (-8)

(a) We have to find the sum of given numbers:

= (- 7) + (- 9) + 4 + 16

= - 7 – 9 + 4 + 16

= - 16 + 20

= 4

Therefore, sum is 4.

(b) We have to find the sum of given numbers:

= 37 + (- 2) + (- 65) + (- 8)

= 37 – 2 – 65 – 8

= 37 – 67 – 8

= 37 – 75

= - 38

Therefore, sum is – 38.
