Exercise 6.2

1.Using the number line write the integer which is.

Try this using numberline.

(a) 3 more than 5 which means (3 + 5) =

(b) 5 more than –5 which means (5 - 5) =

(c) 6 less than 2 which means (-6 + 2 ) =

(d) 3 less than –2 which means (-3 -2) =

2.Use number line and add the following integers.

(a) 9 + (– 6) =

(b) 5 + (– 11) =

(c) (– 1) + (– 7) =

(d) (– 5) + 10 =

(e) (– 1) + (– 3) =

(f) (– 2) + 8 =

3. Add without using number line.

(a) 11 + (– 7) =

(b) (– 13) + (+ 18) =

(c) (– 10) + (+ 19) =

(d) (– 250) + (+ 150) =

(e) (– 380) + (– 270) =

(f) (– 217) + (– 100) =

4.Find the sum of below numbers.

(a) 137 and – 354 =

(b) – 52 and 52 =

(c) – 312, 39 and 192 = -312 + =

(d) – 50, – 200 and 300 = + 300 = .

5.Find the sum.

(a) (– 7) + (– 9) + 4 + 16 = (-7 -9) + (4 + 16) = + = .

(b) (37) + (– 2) + (– 65) + (– 8) = (37) + (-75) = - = .
