Find the sum of:
(a) 137 and – 354
(b) -52 and 52
(c) -312, 39 and 192
(d) -50, -200 and 300
(a) We have to find the sum of given numbers:
= 137 + (-354)
= 137 – 354
= - 217
Therefore, sum is – 217
(b) We have to find the sum of given numbers:
= - 52 + 52
= 0
Therefore, sum is 0
(c) We have to find the sum of given numbers:
= - 312 + 39 + 192
= -312 + 231
= - 81
Thereore, sum is – 81
(d) We have to find the sum of given numbers:
= - 50 + (- 200) + 300
= - 50 – 200 + 300
= - 250 + 300
= 50
Therefore, sum is 50
