Question

Find the value of the following. 

(i) 137 + (- 354) +125 

(ii) (- 312) + 39 + 192 

(iii) 37 +(-3)+ 24 +(-8) 

(iv) 102 + (- 24) + (24) + (- 11)

Answer 1

(i) 137 + (- 354) + 125 = 137 – 354 + 125 = 137 + 125 – 354 = 262 – 354 = – 92 

(ii) (- 312) + 39 + 192 = – 312 + 39 + 192 = – 312 + 231 = – 81 

(iii) 37 + (- 3) + 24 + (- 8) = 37 – 3 + 24 – 8 = 37+ 24 – 3 – 8 = 61 – 11 = 50 

(iv) 102 + (- 24) + (24) + (- 11) = 102 – 24 + 24 – 11 = 102 + 24 – 24 – 11 = 102 – 11 = 91
