Is to realize that the absolute value of a single number, is the distance of how far that number is
from 0.
As such, it is a positive value, and will not be negative, though an absolute value is allowed be
0 itself.
The symbol for representing the absolute value is two vertical lines on either side of the value
concerned.
The Absolute Value can be generalized into the Absolute Value Function.
It is a piecewise function, and is a function very commonly seen in Mathematics.
The function is presented as: f(x) = |x|
If x is a real number, then,
Because the Absolute Value is to be greater or equal to zero.
A negative x value is reversed with a minus sign, and
made positive.
Below is a demonstration with 3 and -3.
Both 3 and -3 are a distance of 3 away from 0.
The Absolute Value Function has some properties that are handy to remember.
