## Haryana Board 6th Class Maths Solutions Chapter 6 Integers Exercise 6.3

Question 1.
Subtract:
(a) 35 – (20)
(b) 72 – (90)
(c) (-15) – (-18)
(d) (-20)-(13)
(e) 23 – (-12)
(f) (-32) – (-40)
Solution:
(a) 35 – (20) = 15.
(b) 72-(90) = -18.
(c) (-15) – (-18) = (-15) + 18 = 3.
(d) (-20) – 13 = -33.
(e) 23-(-12) = 23 + 12 = 35.
(f) (-32) – (-40) = (-32) + 40 = 8.

Question 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) = -9
and (-3)-(-6) = (-3) + 6 = 3
∵ (-9) < 3
∴ (-3) + (-6) < (-3) – (-6)

(b) (-21) – (-10) = -21 + 10 = -11
and (-31) + (-11) = – 42
∵ (-11) > (-42)
∴ (-21) – (-10) > (-31) + (-11)

(c) 45 – (-11) = 45+ 11 = 56
and 57 + (-4) = 53
56 > 53
∴ 45 – (-11) > 57 + (-4)

(d) (-25) – (-42) = (-25) + 42 = 17
and (-42) – (-25) = -42 + 25 = -17,
∵ 17 > -17
∴ (-25) – (-42) > (-42) – (-25).

Question 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) = 0
(d) (-4) + (-8) = -12
(e) 5 + (-15) = -10.

Question 4.
Find the value of:
(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 = 32 – 13 – 8 – 1
= 32 – 22 = 10
(c) (-7) + (-8) + (-90) = -7 – 8 – 90 = -105
(d) 50 – (-40) – (-2) = 50 + 40 + 2 = 92.
