प्रश्न 1.
घटाइए
(a) 35 - (20)
हल:
35 - (20) = (15 + 20) - 20
= 15 + (20 - 20)
= 15 + 0 = 15
(b) 72 - (90)
हल:
72 - (90) = 72 – (72 + 18)
= (72 - 72) + (-18)
= 0 + (- 18) = - 18
(c) (-15) - (-18)
हल:
(- 15) - (-18) = (- 15) + (योज्य प्रतिलोम - 18)
3 - 15 + 18 = - 15 + (15 + 3)
= (- 15 + 15) + 3
= 0 + 3 = + 3
(d) (-20) - (13)
हल:
(-20) - (13) = - 20 - 13
= - (20 + 13) = -33
(e) 23 - (-12)
हल:
- 23 - (- 12) = 23 + 12 = 35
(f) (-32) - (-40)
हल:
(-32) - (-40) = - 32 + 40
= (-32 + 32) + 8
= 0 + 8 = 8

प्रश्न 4.
निम्नलिखित के मान ज्ञात कीजिए
(a) (-7) - 8 - (-25)
हल:
(-7)- 8 - (-25) = - 7 - 8 + 25
= - 15 + 25
= 10
(b) (-13) + 32 - 8 - 1
हल:
(-13) + 32 - 8 - 1 = - 13 - 8 - 1 + 32
= - 22 + 32 = 10
(c) (-7) + (-8) + (-90)
हल:
(-7)+(-8) + (-90) = 5 - 7 - 8 - 90
= - 105
(d) 50 - (-40)- (-2)
हल:
