Absolute value is a function placed on a series of mathematical operations to derive the magnitude of the resulting value. The absolute value of a number is by definition that number's distance from zero on a number line. As such, there are no negative absolute values. Absolute values are first encountered in intermediate algebra classes as a means for understanding the real number system. This function is later revisited in calculus and statistics.
Simplify all terms within the absolute value sign as normal. For example, |3 - 5 + 10|= |8|
Remove the absolute value symbols and remove any negative sign within them. For example, |5 - 8| = |-3| = 3.
Apply any sign that was attached to the absolute value symbol to the resulting integer. For example, -|5 - 2| = -|3|= - (3) = -3.
