(a) (– 7) – 8 – (– 25)

(b) (– 13) + 32 – 8 – 1

(c) (– 7) + (– 8) + (– 90)

(d) 50 – (– 40) – (– 2)

**Solution:**

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

(a) (-7) – 8 – (-25)

= (-7) – 8 + 25

= -15 + 25 = 10

(b) First, let’s add all the positive numbers and all the negative numbers separately

(-13) + 32 – 8 – 1

= 32 - 22

= 10

(c) (- 7) + (- 8) + (- 90)

= – (7 + 8 + 90)

= -105

(d) 50 – (-40) – (-2)

= 50 + 40 + 2

= 92
