Absolute value
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, and |0|
= 0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3.
