**Exercise 6.2**

**Q.1) Using the number line write the integers which is :**

**(a) 3 more than 5**

**(b) 5 more than –5**

**(c) 6 less than 2**

**(d) 3 less than –2**

**Sol.1)** a) To find the integer that is 3 more than 5, we start with 5 and proceed 3 steps to the right as shown below:

**Q.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)
Sol.2) **a) On the number line, we first move 9 steps to the right from 0. Then we move 6 steps to the left from 9 and reach 3.

Hence, (– 1) + (– 2) + (– 3) = -6

f) (– 2) + 8 + (– 4)

On the number line, we first move 2 steps to the left from 0. Then we move 8 steps to the right from -2 and reach 6. Then we move 4 steps to the left from 6 and reach 2.

(– 2) + 8 + (– 4) = 2

**Q.3) Add without using number line:**

**(a) 11 + (–7)**

**(b) (–13) + (+18)**

**(c) (–10) + (+19)**

**(d) (–250) + (+150)**

**(e) (–380) + (–270)**

**(f) (–217) + (–100)**

**Sol.3)** a) 11 + (– 7)

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer. The bigger integer is decided by ignoring the signs of the integers [e.g. (+4) + (–3) = + 1 and (–4) + (+ 3) = – 1].

Subtracting the integers, we get 11 – 7 = 4.

Now put the sign of the bigger integer. The bigger integer is 11 with a positive sign.

So, 11 + (– 7) = 4

b) (– 13) + (+ 18)

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer. The bigger integer is decided by ignoring the signs of the integers [e.g. (+4) + (– 3) = + 1 and (– 4) + ( + 3) = – 1].

Subtracting the integers, we get 18 – 13 = 5.

Now put the sign of the bigger integer. The bigger integer is 18 with a positive sign.

So, (– 13) + (+18) = 5

c) (−10) + (+ 19)

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer. The bigger integer is decided by ignoring the signs of the integers [e.g. (+4) + (– 3) = +1 and (– 4) + ( + 3) = −1].

Subtracting the integers, we get 19 – 10 = 9.

Now put the sign of the bigger integer. The bigger integer is 19 with a positive sign.

So, (– 10) + (+ 19) = 9

d) (– 250) + (+150)

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer. The bigger integer is decided by ignoring the signs of the integers [e.g. (+4) + (– 3) = +1 and (– 4) + (+ 3) = −1].

Subtracting the integers, we get 250 – 150 = 100.

Now put the sign of the bigger integer. The bigger integer is 250 with a negative sign.

So, (-250) + (+150) = (-100)

e) (– 380) + (– 270)

When we have the same sign, add and put the same sign. When two negative integers are added, we get a negative integer [e.g. (– 2) + (−1) = −3].

Adding the numbers, we get 380 + 270 = 650

As both are negative integers, the sum is also a negative integer.

So, (– 380) + (– 270) = (– 650)

f) (−217) + (−100)

When we have the same sign, add and put the same sign. When two negative integers are added, we get a negative integer [e.g. (– 2) + (−1) = −3].

Adding the numbers, we get 217 + 100 = 317

As both are negative integers, the sum is also a negative integer.

So, (– 217) + (– 100) = (– 317)

**Q.4) Find the sum of :**

**(a) 137 and – 354 (b) – 52 and 52 (c) – 312, 39 and 192**

**(d) –50,–200 and 300**

**Sol.4)** a) 137 and – 354

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer.

137 + (– 354) = – 217

[Subtract the numbers: 354 – 137 = 217. Put the sign of the bigger integer.]

b) – 52 and 52

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer.

−52 + 52 = 0

[Subtract the numbers: 52 – 52 = 0]

c) – 312, 39 and 192

When one positive and one negative integers are added we subtract them and put the sign of the bigger integer.

−312 + 39 + 192 = −81

[Subtract the numbers: 312 – 39 = 273. Put the sign of the bigger integer, (−312).

So, −273 + 192 = −81]

d) −50, – 200 and 300

(a) When we have the same sign, add and put the same sign.

(b) When one positive and one negative integers are added we subtract them and put the sign of the bigger integer.

(– 50) + (−200) + (300) = 50

[The integers 50 and 200 have the same sign. So we add and put the same sign as -250.

Now (-250) and 300 are added. So, we subtract them and put the sign of the bigger integer as +50.]

**Q.5) Find the sum:**

**(a) (– 7) + (– 9) + 4 + 16 (b) (37) + (– 2) + (– 65) + (– 8)**

**Sol.5)** a) (–7) + (–9) + 4 + 16

= –7 – 9 + 4 + 16

= –16 + 20

= 4

b) 37 + (–2) + (–65) + (–8)

= 37 – 2 – 65 – 8

= 37 – 75

= –38

**Exercise** **6.3**

**Q.1) Find**

**(a) 35 – (20) (b) 72 – (90) (c) (– 15) – (– 18)**

**(d) (–20) – (13) (e) 23 – (– 12) (f) (–32) – (– 40)**

**Sol.1)** (a) 35 – (20) = 15 [Subtract 35 and 20 and put the sign of the bigger number 35, which is positive]

(b) 72 – (90) = −18 [Subtract 72 and 90 and put the sign of the bigger number 90, which is negative.]

(c) (– 15) – (– 18)

To subtract two integers, we add the additive inverse of the integer that is being subtracted.

Additive inverse of (-18) is +18.

(– 15)– (– 18) = (– 15) + (18) = +3

(d) (– 20)– (13) = −33 [Both the integers have the same sign, So, we add the integers and put the same sign.]

(e) 23 – (– 12)

To subtract two integers, we add the additive inverse of the integer that is being subtracted.

Additive inverse of (−12) is +12.

23 – (– 12) = 23 + 12 = 35

(f) (−32) – (– 40)

To subtract two integers, we add the additive inverse of the integer that is being subtracted.

Additive inverse of (−40) is +40

(– 32)– (– 40) = (– 32) + 40 = 8 [Subtract 40 and 32 and put the sign of the bigger integer 40, which is positive.]

**Q.2) Fill in the blanks with >, < or = sign.**

**(a) (– 3) + (– 6) ______ (– 3) – (– 6)**

**(b) (– 21) – (– 10) _____ (– 31) + (– 11)**

**Sol.2)** (a) (– 3) + (– 6) ______ (– 3) – (– 6)

**L.H.S**

(– 3) + (– 6) = (-9) [Both the integers have the same sign. So, we add the integers and put the same sign.]

**R.H.S**

(– 3) – (– 6) = (-3) + 6 = 3 [To subtract two integers, we add the additive inverse of the integer that is being subtracted.]

(−9) < 3

(– 3) + (−6) < (– 3) – (– 6)

(b) (– 21) – (– 10) _____ (– 31) + (– 11)

**L.H.S**

(– 21) – (– 10) = (-21) + 10 = -11 [To subtract two integers, we add the additive inverse of the integer that is being subtracted.]

**R.H.S**

(– 31) + (– 11) = (-41) [Both the integers have the same sign. So, we add the integers and put the same sign.]

(−11) > (−41)

(– 21) – (– 10) > (– 31) + (– 11)

(c) 45 – (– 11) ______ 57 + (– 4)

**L.H.S**

45 + 11 = 56

**R.H.S**

57 + (-4) = 53

56 > 53

45 – (– 11) > 57 + (– 4)

(d) (– 25) – (– 42) _____ (– 42) – (– 25)

**L.H.S**

(-25) – (-42) = (-25) + 42 = 17

**R.H.S**

(-42) – (-25) = (-42) + 25 = (-17)

17 > (-17)

(– 25) – (– 42) > (– 42) – (– 25)

**Q.3) Fill in the blanks.**

**(a) (– 8) + _____ = 0**
