# How do you simplify abs(pi)?

Jul 25, 2016

As $\pi$ is a positive transcendental (never-ending) string of digits = 3.14159265... it is tautological to say $| \pi |$.

#### Explanation:

Already $\pi$ is a positive constant. So, saying $| \pi |$ is tautology.

$| \pi | = \pi$

#### Explanation:

The absolute value functuon |•| gives the distance of a real number from $0$ on the number line. That is,

$| x | = x$ if $x \ge 0$
$| x | = - x$ if $x < 0$

As $\pi > 0$, then, $| \pi | = \pi$
