Evaluating an absolute value expression is when you calculate the value of the problem. Remember when you find the absolute value of a number the answer is always positive. However when absolute values are apart of a larger expression the overall value can be any real number- positive or negative.

Key concepts to remember:

* the absolute value is the “distance” a number is from zero on the real number line
* distance is measured in positive units- therefore the absolute value of a number is always positive
* absolute values are common in algebraic expressions- so you need to really understand them



some key topics that involve evaluating absolute value:

* number operations
* order of operations
* real numbers
* absolute value equations and inequalities
