Absolute value

of the absolute value function for real numbers The absolute value of a number may be thought of as its distance from zero. In mathematics, the absolute value or modulus of a real number $x$, is the non-negative value without regard to its sign. Namely$|x|=x$ if is a positive number, and $|x|=-x$ if $x$ is negative (in which case negating $x$ makes $-x$ positive), and For example, the absolute value of 3 and the absolute value of −3 is The absolute value of a number may be thought of as its distance from zero.
