(1)
(i) (+ 14) – (+ 16)
= 14 – 16
= – 2
(ii) (+ 25) – (+ 21)
= 25 – 21
= 4
(iii) (+ 34) – (- 19)
= 34 + 19
= 53
(iv) (-15) – (- 27)
= – 15 + 27
= 12
(v) (- 25) – (+ 13)
= – 25 – 13
= – 38
(vi) (- 16) – (- 10)
= – 16 + 10
= – 6
(vii) (+ 31) – (- 12)
= 31 + 12
(viii) (- 31) – (- 45)
= – 31 + 45
= 14
(ix) (-21) – (+ 21)
= – 21 – 21
= – 42
(2)
(a) (+ 13) + (- 8) = (+ 3) – (- 2)
=> 13 – 8 = 3 + 2
= > 5 = 5
(b) (- 12) – (- 10) > (- 9) + (+ 3)
= – 12 + 10 > – 9 + 3
= – 2 > – 6
(c) (+ 35) – (- 5) = (- 24) – (- 64)
=> 35 + 5 = – 24 + 64
=> 40 = 40
(d) (- 18) – (+ 6) < (- 18) – (- 6)
=> – 18 – 6 < – 18 + 6
=> – 24 < – 12
(e) (- 45) – (- 52) > (- 52) – (- 45)
=> – 45 + 52 > – 52 + 45
= 7 > 7
(f) (+ 25) – (- 19) > (- 25) – (+ 19)
= 25 + 19 > – 25 – 19
= 44 > – 44
(3)
(a) (- 3) + 3 = 0
(b) (+ 16) + (- 16) = 0
(c) (- 9) + (- 6) = – 15
(d) (- 3) + (- 7) = (- 10)
(4)
(a) (-5) + (- 7 এর বিপরীত সংখ্যা) – (- 5)
= – 5 + 7 + 5
= 7
(b) 12 – (- 3) + (+ 6 এর বিপরীত সংখ্যা)
= 12 + 3 + (- 6)
= 15 – 6
= 9
(c) 15 – (+ 4) + (+ 9 এর বিপরীত সংখ্যা)
= 15 – 4 + (- 9)
= 15 – 4 – 9
= 11 – 9
= 2
(d) (+ 20 র বিপরীত সংখ্যা) – (- 7 র বিপরীত সংখ্যা) – (- 8)
= (+ 20) – (+ 7) + (8)
= 20 – 7 + 8
= 13 + 8
= 21
(8)
(i) (+ 5), (+ 3), (+ 2)
∴ (+ 5 + 3 + 2)
= 9
(ii) (+ 5), (- 3), (+ 2)
= (+ 5) + (- 3) + (+ 2)
= 5 – 3 + 2
= 4
(iii) (- 5), (- 3), (+ 2)
∴ (- 5) + (- 3) + (+ 2)
= – 5 – 3 + 2
= – 8 + 2
= – 6
(iv) (- 5), (- 3), (- 2)
∴ (- 5) + (- 3) + (- 2)
= – 5 – 3 – 2
= – 8 – 2
= – 10
