We will have that Absolute Value is the magnitude of a value and is denotated as follows:
| x | : The absolute value of x.
When we speak about magnitude we refer just to possitive values. For example:
*The absolute value of 3:
| 3 | = 3
*The absolute value of -45:
| -45 | = 45
From this, we can clearly see that we "keep the number" but not the sign.
