The absolute value of x is always either positive or zero, but never negative. From an analytic geometry point of view, the absolute value of a real number is that number's distance from zero along the real number line. The absolute value of the difference of two real numbers is the distance between them.
Explanation:
Absolute value is always positive. Since it's the distance a number is from 0, it would always be positive. So, the absolute value of positive 5, would be positive 5.
