(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

Solution :

(a) Given, 3 more than 5

Using number line :

= 3 + 5

= 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)

Solution :

(a) 11 + (- 7)

= 11 – 7

= 4

(b) (- 13) + (+ 18)

= (- 13) + 18

= 5

(c) (- 10) + (+ 19)

= (- 10) + 19

= 9

(d) (- 250) + (+ 150)

= (- 250) + 150

= 100

(e) (- 380) + (- 270)

= – 380 – 270

= – 550

(f) (- 217) + (- 100)

= – 217 – 100

= – 317

(4) Find the sum of :

(a) 137 and – 354

(b) – 52 and 52

(c) – 312, 39 and 192

(d) – 50, – 200 and 300

Solution :

(a) 137 and – 354

= 137 + (- 354)

= 137 + (- 354)

= – 217

(b) – 52 and 52

= – 52 + 52

= 0

(c) – 312, 39 and 192

= – 312 + 39 + 192

= – 312 + 231

= – 81

Now, – 312 + 39 + 192

= – 81

(d) – 50, – 200 and 300

= (- 50)+ (- 200) + 300

= -250 + 300

= 50

Now, (- 50) + (- 200) + 300

= 50

(5) Find the sum :

(a) (- 7) + (- 9) + 4 + 16

(b) (37) + (- 2) + (- 65) + (- 8)

Solution :

(a) (- 7) + (- 9) + 4 + 16

= – 7 – 9 + 4 + 16

= -16 + 20

= 4

Hence, the sum will be 4

(b) (37) + (- 2) + (- 65) + (- 8)

= 37 – 2 – 65 – 8

= 37 – 75

= -38

Thus, the sum will be -38

Integers Exercise 6.3 Solution :

(1) Find

(a) 35 – (20)

(b) 72 – (90)

(c) (- 15) – (- 18)

(d) (-20) – (13)

(e) 23 – (- 12)

(f) (-32) – (- 40)

Solution :

(a) 35 – (20)

= 35 -20

= 15

(b) 72 – (90)

= 72 – 90

= -18

(c) (– 15) – (– 18)

= (– 15) + 18

= 3

(d) (–20) – (13)

= –20 – 13

= -33

(e) 23 – (– 12)

= 23 + 12

= 35

(f) (–32) – (– 40)

= (–32) + 40

= 8

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

(a) (-3) + (-6) ___ (-3) -(-6)

(b) (-21) -(-10) ___ (-31) + (-11)

(c) 45 -(-11) ___ 57 + (-4)

(d) (-25) -(-42) ___ (-42) -(-25)

Solution :

(a) = (-3) – 6 (-3) + 6)

= -9 < 3

= (-3) + (-6) -41

= (-21) – (-10) > (-31) + (-11)

(c) = 45 + 11 57 – 4

= 56 > 53

= 45 – (-11) > 57 + (-4)

(d) = (-25) + 42 (-42) + 25

= 17 >  – 17

= (-25) – (-42) > (-42) -(-25)

(3) Fill in the blanks :

(a) (– 8) + __ = 0

(b) 13 + __ = 0

(c) 12 + (– 12) = __

(d) (– 4) + __ = – 12

(e) __ – 15 = – 10

Solution :

(a) (– 8) + 8 = 0

(b) 13 + (-13) = 0

(c) 12 + (– 12) = 12 – 12 = 0

(d) – 12 + 4 = –8

(e) – 10 + 15 = 5

(4) Find

(a) (– 7) – 8 – (– 25)

(b) (– 13) + 32 – 8 – 1

(c) (– 7) + (– 8) + (– 90)

(d) 50 – (– 40) – (– 2)

Solution :

(a) (– 7) – 8 – (– 25)

= (– 7) – 8 + 25

= – 15 + 25

= 10

(b) (– 13) + 32 – 8 – 1

= (– 13) + 32 – 9

= 32 – 22 =10

(c) (– 7) + (– 8) + (– 90)

= (– 7) + (– 8) + (– 90)

= – 7 – 8 – 90

= (– 7) + (– 8) + (– 90) = – 105

(d) 50 – (– 40) – (– 2)

= 50 – (– 40) – (– 2)

= 50 + 40 + 2

= 92
