Question 1.
Manasa has borrowed ₹ 50 and Swetha has borrowed ₹ 20 from their mother. How will you represent this on the number line ₹ Suppose their father gave them ₹ 100 each as pocket money, who will have more money after clearing the debit ?
Answer:
If each of them get ₹ 100 from their father
then amount at Manasa = 100 – 50 = ₹ 50
then amount at Swetha = 100 – 20 = ₹ 80
∴ Amount of Swetha is greater than that of Manasa.

Question 1.
Rajesh has a shop CM thp ground floor of a building. There are stairs going up to the terrace and stairs going down to the godown, where goods are stored.
Everyday his daughter Hasini, after coming back from school goes up to the terrace to play. She helps father in arranging things in the godown at night.
Observe the picture and try to answer the questions using integers marked on the steps.
(i) Go 7 steps up from the shop.
(ii) Go 3 steps down from the ground floor.
(iii) Go 5 steps up from the ground floor and then go 3 steps further up from there.
(iv) Go 4 steps down from the ground floor and then further 3 steps from there.
(v) Go down 5 steps down from the ground floor and 10 steps up fmin there.
(vi) Go 8 steps up from the ground floor and come down 9 steps down from there.
Answer:
(i) +7
(ii) -3
(iii) 5 + 3 = + 8
(iv) (-4) + (-3) = -7
(v) (-5) + 10 = +5
(vi) (8) + (-9) = (—1)

Question 1.
Find the values of the following.
(i) -7 + 8
(ii) -3 + 5
(iii) – 3 – 2
(iv) + 7 – 10
Answer:
(i) (- 7) + (8)
= (- 7) + (+ 7) + (+1)
= [(-7) + (+7)] + (+1)
= 0 + 1 = 1
(ii) (- 3) + (+ 5)
= [(-3) + (+3)] + (+2)
= 0 + 2 = 2
(iii) (-3) +(-2)
= [-(3 + 2)] = -5
(iv) (+7) + (-10)
= (+7) + [(-7) + (-3)]
= [(+7) + (-7)] + (-3)
= 0 – 3
= – 3

Question 1.
Find the value of the following using a number line.
(i) (- 3) + 5
(ii) (- 5) + 3
Make your own two new questions and solve them using the number line.
Answer:
(i) (- 3) + 5 = (- 3) + (3 + 2) = [- 3 + 3] + 2 = 0 + 2 = 2
(ii) (- 5) + 3 = [(- 3) + (- 2)] + 3 = [(- 3) + 3] + (- 2) = 0 + (- 2) = – 2
Ex: (i) (-4) + 1 = -3
(ii) 6 + (-4) = 2
Question 2.
Find the solution of the following:
(i) (+5) + (-5)
(ii) (+6) + (-7)
(iii) (-8) + (+2)
Ask your Mend to give five such questions and solve them.
Answer:
(i) (+ 5) + (- 5) = 5 – 5 = 0
(ii) (+ 6) + (- 7) = (+6) + [(- 6) + (- 1)] = [(+ 6) + (-6)] + (- 1) = 0 + (- 1) = – 1
(iii) – 8 + (+ 2) = [(- 6) + (- 2)] + (+ 2) = (- 6) + [(- 2) + (+ 2)] = (- 6) + 0 = – 6
Five related problems.
(i) (-6) + (-3)
(ii) (+8) + (-5)
(iii) (-16) + 15
(iv) 10 + (-6)
(v) (+11) + (-12)
Answer:
(i) (- 6) + (- 3)
= (- 6) + (- 3)
= – 9
(ii) (+ 8) + (- 5) = [(+ 3) + (+ 5)] + (-5)
= (+ 3) + [(+ 5) + (- 5)]
= (+ 3) + 0 = 3
(iii) (- 16) + 15
= [(- 15) + (- 1)] + 15
= (- 15) + (+ 15) + (- 1)
= – 1
(iv) 10 + (- 6)
= [(+ 4) + (+ 6)] + (- 6)
= (+4) + [(+ 6) + (- 6)]
= (+ 4) + 0 = + 4
(v) (+ 11) + (- 12)
= (+ 11) + [(- 11) + (- 1)]
= [(+ 11) + (- 11)] + (- 1)
= 0 + (- 1)
= – 1

Question 1.
Find the solution of the following.
(a) -5- (-3)
(b) – 7 – (+2)
(c) – 7 – (-5)
(d) 3 – (-4)
(e) 5 – (+7)
(f) 4 – (- 2)
Sol.
(a) – 5 – (- 3) = – 5 + 3 = – 2
(b) – 7 – (+2) = – 7 – 2 = – 9
(c) – 7 – (- 5) = – 7 + 5 = – 2
(d) 3 – (- 4) = 3 + 4 = + 7
(e) 5 – (+ 7) = 5 – 7 = – 2
(f) 4 – (- 2) = 4 + 2 = + 6

Question 1.
Observe that as the number we subtract from 3 is decreasing, the result obtained is increasing. Is it true for all integer’s?
3 – 3 = 0
3 – 2 = 1
3 – 1 = 2
3 – 0 = 3
3 – (-1) = 4
3 – (- 2) = 5
3 – (- 3) = 6
Answer:
No, it is not true for all the integers.
Since 3 – 4 = – 1
3 – 5 = – 2
3 – 6 = – 3 it is decreasing.
