Negative Numbers and Integers Exercise 4B Solution :
Question no – (1)
Solution :
(a) (+ 75) + (+ 43)
= 75 + 43
= 118
(b) 45 + (- 34)
= 45 – 34
= 11
(c) (- 90) + 54
= – 90 + 54
= – 36
(d) (- 23) + (- 12)
= – 23 – 12
= – 35
Question no – (2)
Solution :
(a) 974 – (342)
= 974 – 342
= 632
(b) (- 67) – (23)
= – 67 + 23
= – 44
(c) (- 78) – (- 2)
= – 78 + 2
= – 76
