<P> In mathematics , the absolute value or modulus x of a real number x is the non-negative value of x without regard to its sign . Namely , x = x for a positive x , x = − x for a negative x ( in which case − x is positive ) , and 0 = 0 . For example , the absolute value of 3 is 3 , and the absolute value of − 3 is also 3 . The absolute value of a number may be thought of as its distance from zero . </P>
