Q1 Using the number line write the integer which is :
(a) more than
(b) more than
(c) less than
(d) less than
Answer: (a) more than
The answer is 5 + 3 = 8

The answer is 5 + 3 = 8
Q2 Use number line and add the following integers :
(a)
(b)
(c)
(d)
(e)
(f)
Answer: Addition by using the number line method-
(a)
Initially, move 0 to 9 and then 6 number left to the 9 on the numberline.
Q3 Add without using number line :
(a)
(b)
(c)
(d)
(e)
(f)
Answer: In addition without using the number line, in this method, we have to split one number according to the other number such that .
Now,
(a) = 4 + (7)+ (-7) = 4
(b)
= -13 + (13) + 5
= 5
(c)
= (- 10) + (10) + 9
= 9
(d)
= (- 100) + (- 150) + (150)
= - 100
(e)
= - (380 + 270 )
= - 650
(f)
= - (217 + 100)
= - 317
(a)
(b)
(c)
(d)
Answer: It is known that the sum of .
Therefore,
(a) the sum of
= 137 + (-137) + (- 217)
= - 217
(b) the sum of
= -52 + 52 = 0
(c) the sum of
= (- 231) + (81) + (39 + 192 )
= (- 81) + (- 231) + (231)
= - 81
(d) the sum of
= - (50 + 200 ) + (300)
= - 250 + (250) + 50
= 50
(a)
(b)
Answer: It is known that the sum of .
Therefore,
(a)
= - (9 + 7) + 4 + 16
= (- 16) + 4 + 16
= 4
Also we can split the 16 into (- 9 and -7 ).
(b)
= 37 + (- 37) + (- 28) + (-2) + (- 8)
= 0 - (37 + 28 + 8)
= - 73

Q1 Find
(a)
(b)
(c)
(d)
(e)
(f)
Answer: It is known that the sum of .
So, we have to split the number in order to cancel out with other numbers.
(a)
= 15 + (- 20) + 20
= 15 + 0 = 15
(b)
= 72 - (72) - 18
= 0 - 18 = -18
(c)
= (- 15) + 18
= (- 15) + (15) + 3
= 0 + 3 = 3
(d)
= - (20 + 13 )
= -33
(e)
= 23 + 12
= 35
(f)
= (- 32) + 40
= (- 32) + (32) + 8
= 0 + 8
= 8
Q2 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)
Answer: (a) (– 3) + (– 6) ______ (– 3) – (– 6)
LHS - 3 - 6 = -9
RHS - 3 + 6 = +3
Hence LHS < RHS
(b) (– 21) – (– 10) _____ (– 31) + (– 11)
LHS - 21 +10 = -11
RHS -31 - 11 = -42
Hence LHS > RHS
(c) 45 – (– 11) ______ 57 + (– 4)
LHS 45 + 11 = 66
RHS 57 - 4 =53
Hence LHS > RHS
(d) (– 25) – (– 42) _____ (– 42) – (– 25)
LHS - 25 + 42 = 17
RHS -42 + 25 = -17
Hence LHS > RHS
(a) (– 8) + _____ = 0
(b) 13 + _____ = 0
(c) 12 + (– 12) = ____
(d) (– 4) + ____ = – 12
(e) ____ – 15 = – 10
Answer: a) (– 8) + _____ = 0
Since we know that, . Therefore, the blank space should be + 8.
(b) 13 + _____ = 0
The sum is zero. Therefore it should be additive inverse of 13. -13( is the answer)
(c) 12 + (– 12) = ____
Since we know that, So, the answer is Zero (0)
(d) (– 4) + ____ = – 12
The integer in blank space should be -8
(e) ____ – 15 = – 10
The integer in blank space should be +5
Q4 Find
(a)
(b)
(c)
(d)
Answer: We already know that the sum of the additive inverse is Zero ( )
(a)
(b)
(c)
(d)
