This section is an exploration of the absolute value function; specifically how and why they are used and their mechanics.

By the end of this section students should be able to:

Identify an absolute value in expressions and equations
Correctly introduce absolute values when they are needed during work.
Solve absolute values both analytically and geometrically.
Translate appropriate phrases into absolute value expressions, or vice versa.

In this section we aim to answer the following questions

When and why do we need absolute values?
How do absolute values and piece-wise functions relate to one another?
