Exercise 7 Page 1

Absolute value will always be non-negative. Start by calculating the expression inside the absolute value.

$1$

The absolute value of a number is the non-negative value of that number.

∣ a ∣ = a and ∣ - a ∣ = a

We can start by calculating the expression inside the absolute value.

∣ - 8 - (- 7) ∣

$a - (- b) = a + b$

∣ - 8 + 7 ∣

Add terms

∣ - 1 ∣

$∣ - 1 ∣ = 1$
