Exercise 6 Page 51

Absolute value will always be non-negative.

Practice makes perfect

The absolute value of a number is the non-negative value of that number. |a| = a and |- a| = aWe can start by calculating the expression inside the absolute value.

- 5+|3|

|3|=3

-5+3

Add terms

- 2

Now that the expression has been simplified, we can graph - 2 as a closed circle on a number line.
