Absolute value is the distance from a number to zero on a number line, and it is always positive since distance cannot be negative. The lesson includes examples of how to calculate the absolute value of both positive and negative numbers, as well as expressions. To simplify an absolute value expression, you need to first simplify what is inside the absolute value brackets.
