**Class 6 | Mathematics | Chapter 6| Integers****| Exercise 6.2**

**Question 1.** Using the number line write the integer which is :

(a) 3 more than 5

(b) 5 more than –5

(c) 6 less than 2

(d) 3 less than –2

**Answer :**

**(c)** -4

**Question 2**. Use number line and add the following integers :

(a) 9 + (– 6)

(b) 5 + (– 11)

(c) (– 1) + (– 7)

(d) (– 5) + 10

(e) (– 1) + (– 2) + (– 3)

(f) (– 2) + 8 + (– 4)

**Answer :**

**Question 3**. Add without using number line :

(a) 11 + (– 7)

(b) (– 13) + (+ 18)

(c) (– 10) + (+ 19)

(d) (– 250) + (+ 150)

(e) (– 380) + (– 270)

(f) (– 217) + (– 100)

**Answer :**

(a) 11 + (–7) = 11 – 7 = 4

(b) (–13) + 18 = 5

(c) (–10) + (+19) = –10 + 19 = 9

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

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

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

**Question 4**. Find the sum of :

(a) 137 and – 354

(b) – 52 and 52

(c) – 312, 39 and 192

(d) – 50, – 200 and 300

**Answer :**

(a) 137 + (–354) = 137 – 354 = –217

(b) (–52) + 52 = 0

(c) (–312) + 39 + 192 = –312 + 231 = –81

(d) (–50) + (–200) + 300 = –50 – 200 + 300 = –250 + 300 = 50

**Question 5.** Find the sum :

(a) (– 7) + (– 9) + 4 + 16

(b) (37) + (– 2) + (– 65) + (– 8)

**Answer :**

(a) (–7) + (–9) + 4 + 16

= –7 – 9 + 4 + 16

= –16 + 20

= 4

(b) 37 + (–2) + (–65) + (–8)

= 37 – 2 – 65 – 8

= 37 – 75

= –38
