# Add without using number line :

(a) 11 + (– 7)

(b) (– 13) + (+ 18)

(c) (– 10) + (+ 19)

(d) (– 250) + (+ 150)

(e) (– 380) + (– 270)

(f) (– 217) + (– 100)

**Solution:**

We use the concepts of positive and negative integers and addition to add the given integers.

(a) 11 + (-7) = 11 - 7 = 4

(b) (-13) + (+18) = -13 + 18 = 5

(c) (-10) + (+19) = -10 + 19 = 9

(d) (-250) + (+150) = - 250 + 150 = -100

(e) (-380) + (-270) = -380 - 270 = – (380 + 270) = - 650

(f) (-217) + (-100) = -217 - 100 = – (217 + 100) = - 317
