Absolute Value: Also known as
The absolute value of $x$ is sometimes called the modulus or magnitude of $x$, but note that modulus has a more specialized definition in the domain of complex numbers, and that magnitude has a more specialized definition in the context of vectors.
Some sources refer to it as the size of $x$.
Some sources call it the numerical value.
