1. Use the number line and find the sum of the following.

(i) 8 + (-5)

Ans: 8 + (-5)

First we move to the right of 0 by 8 steps reaching at 8. Then we move 5 steps to the left of 8 reaching 3. Thus 8 + (-5) = 3.

(ii) 7 + (- 3) 

Ans: 7 + (- 3)

First we move to the right of 0 by 7 steps reaching at 7. Then we move 3 steps to the left of 7 reaching 4.

(iii) – 8 + (-7) 

Ans: – 8 – 7 

First we move to the left of 0 by – 8 steps reaching at – 8. Then we move to the 0 tp -7  steps reaching -15

Thus – 8 – 7  = – 15

Thus, 7 + (-3) = 4.

(iv) – 12 + 8

Ans: – 12 + 8

First we move to the left of 0 by 12 steps reaching at 12 Then we move 8 steps to the right of 8 reaching -4

Thus, -12 + 8 = – 4.

(v) – 2 + 5 + (– 3)

Ans: – 2 + 5 + (– 3)

On the number line, we first move 2 steps to the left of reaching (-2), then we move 5 steps to the right of -2 reaching 3. Again, we move 3 steps to the left of 3 reaching 0.

Thus, -2 + 5 + (-3) = 0

(vi) -3 + -4 + (-2)

Ans: -3 + (-4) + (-2)

On the number line, we first move 3 steps to the left of reaching -3, then we move 4 steps to the left of this point reaching -7 and at last we move 2 steps to the left of -7 reaching -9.

Thus, -3 + (-4) + (-2 = -9

2. Add the following-

(i) – 3 + 0

Ans: – 3 + 0 = -3

(ii) 3 + 0

Ans: 3 + 0 = 3

(iii) 0 + (-9)

Ans: 0 + (-9) = – 9

3. Find the sum of-

(i) 308 and -470

Ans: 308 + (-470)

= 308 – 470

= – 162

(ii) 614 and – 312

Ans: 614 + (-312)

= 614 – 312

= 302

(iii) -306, -501 and -409

Ans: – 306 + (-501) + (-409)

= – 306 – 501 – 409

= – 807 – 409

= – 1216

4. Using the number line find the following-

(i) The integer which is 5 more than -5.

Ans: 

If 5 more than -5, then the integer will be 0.

(ii) The integer which is 2 more than- 7.

Ans: 

If 2 more than – 7, then the integer will be – 5.

5. Fill in the blanks:

(i) (-8) + ______________ = 0

Ans: (- 8) + 8 = 0

(ii) -15 ______________ = 0

Ans: -15 -(-15) = 0

(iii) 15- (-15) = _______________.

Ans: 15- (-15) = 30

(iv) _____________ – (-8) = -12

Ans: -20 – (-8) = -12

6. Fill in the blanks (>, < or = sign)

(i) -9 + (-7) _____________ (-7) + (-9)

Ans: -9 + (-7) = (-7) + (-9)

(ii) -11 -9 ______________ -9 + 11

Ans: -11 -9 < -9 + 11

(iii) -35 + 20 ______________ -10 -5

Ans: -35 + 20 = -10 -5

(iv) 40 + (-30) ______________ – 20 + (-10)

Ans: 40 + (-30) > -20 + (-10)

(v) -15 – (-8) ______________ 15-8

Ans: -15 – (-8) < 15 -8

7. Subtract the following using number line.

(i) Subtract 142 from -120

Ans: – 120 – 140

= – 260

(ii) Subtract – 250 from – 150

Ans: – 250 – (-150)

= – 250 + 150

=  – 100

(iii) Subtract 4000 from -5080 

Ans: – 5080 – 4000

=  -5080  – 4000

= – 9080

(iv) Subtract 3000 from – 10000 

Ans: 10000 – (-3000)

=  – 10000 + 3000

= – 10000 + 3000

=  – 7000

9. Simplify-

(i) – 97 + (-18) – 47 + 57

Ans: – 97 + (-18) – 47 + 57

= 57 – (97 – 18 – 47)

= 57 – 162

= –  105

(ii) -26 – (-48) – 50 – (-20) -10

Ans: = – 26 + 48 – 50 + 20 – 10

= – 26 – 50 – 10 + 48 + 20

= – (26 + 50 + 10) + 68

= – 86 + 68

= – 18

(iii) 50 – 18 – (-12) + (-12)

Ans: = 50 – 18 + 12 – 12

= 50 + 12 – 18 – 12

= 62 – 30

= 32

10. Which integer is to be added to – 32 to get the sum 0?

Ans: The required integer to be added – 32 + 32 = 0

11. Sum of two integers is – 410. One of them is 180 find the other.

Ans: Sum of two integers = – 410

One of them = 180

∴ The order integer = – 410 – (180)

= – 410 – 180 = – 590

12. What number is to be subtracted from – 80 to get the difference 0?

Ans: A negative integer = – 80

And difference = 0

∴ The required integer = – 80 – 0 = – 80
