Find
(a) 35 – (20) (b) 72 – (90)
(c) (– 15) – (– 18) (d) (–20) – (13)
(e) 23 – (– 12) (f) (–32) – (– 40)

Solution:

We use the concepts of positive and negative integers and subtraction to find the values of the given expressions.

(a) 35 – (20) = 35 - 20 = 15

(b) 72 – 90 = -18

(c) (- 15) – (- 18) = (-15) + (18) = 3

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

(e) 23 – (- 12) = 23 + 12 = 35

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