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

(b) 72 – (90)
= 72 – (72 + 18)
= 72 – 72 – 18
= 0 – 18
= – 18

(c) ( – 15) – ( – 18)
= ( – 15) + (योज्य प्रतिलोम – 18)
= – 15 + 18
= – 15 + (15 + 3)
= – 15 + 15 + 3
= 0 + 3
= 3

(d) ( – 20) – (13)
= – 20 – 13
= – (20 + 13)
= – 33

(e) 23 – ( – 12)
= 23 + 12
= 35

(f) ( – 32) – ( – 40)
= – 32 + 40
= – 32 + (32 + 8)
= 32 + 32 + 8
= 0 + 8
= 8

प्रश्न 2.
रिक्त स्थानों को >, < या = से भरिए
हल :
(a) ( – 3) + ( – 6) < ( – 3) – ( – 6)
(b) ( – 21) – ( – 10) > ( – 31) + ( – 11)
(c) 45 – ( – 11) > 57 + ( – 4)
(d) ( – 25) – ( – 42) > ( – 42) – ( – 25)

प्रश्न 3.
रिक्त स्थानों को भरिए
(a) ( – 8)+ …. = 0
(b) 13 + …. = 0
(c) 12 + ( – 12) = …..
(d) ( – 4)+ …. = -12
(e) …. – 15 = – 10
हल :
(a) 8,
(b) – 13,
(c) 0,
(d) – 8,
(e) 5.

प्रश्न 4.
निम्नलिखित के मान ज्ञात कीजिए
(a) ( – 7) – 8 – ( – 25)
(b) ( – 13) + 32 – 8 – 1
(c) ( – 7) + ( – 8) + ( – 90)
(d) 50 – ( – 40) – ( – 2)
हल :
(a) ( – 7) – 8 – ( – 25)
= ( – 7) + ( – 8) + 25
= – 15 + 15 + 10
= 0 + 10
= 10

(b) ( – 13) + 32 – 8 – 1
= ( – 13) + 32 + ( – 8) + ( – 1)
= – (13 + 8 + 1) + 32
= – 22 + 32
= – 22 + 22 + 10
= 0 + 10
= 10

(c) ( – 7) + ( – 8) + ( – 90)
= – 7 – 8 – 90
= – 105

(d) 50 – ( – 40) – ( -2)
= 50 + ( + 40) + (+ 2)
= 50 + 40 + 2
= 92
