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
