The absolute value of a number may be thought of as its distance from zero. 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| = âx for a negative x (in which case âx is positive), and |0| = 0. For example, the absolute value of 3 is 3, and the absolute value of â3 is also 3. The absolute value of a number may be thought of as its distance from zero. Generalisations of the absolute value for real numbers occur in a wide variety of mathematical settings.
