Question

Compute the following :

(i) 7 + 4 

(ii) 8+( – 3) 

(iii) 11 + 3 

(iv) 14 + ( – 6) 

(v) 9 + ( – 7) 

(vi) 14+( – 10) 

(vii) 13 + ( – 15) 

(viii) 4 + ( – 4) 

(ix) 10 +( – 2) 

(x) 100 +( – 80) 

(xi) 225 +( – 145)

Answer 1

(i) 7 + 4 = 11 

(ii) 8 +( – 3) = 5 

(iii) 11 + 3 = 14 

(iv) 14 + ( – 6) = 8

(v) 9 + ( – 7) = 2 

(vi) 14 +( – 10) = 4 

(vii) 13 + ( – 15) = -2 

(viii) 4 + ( – 4) = 0 

(ix) 10 +( – 2) = 8 (x) 100 +( – 80) = 20 

(xi) 225 +( – 145) = 80
