If you like to talk about modulus in mathematics, you have to check out Facts about Absolute Value. The sign of absolute value is |x|. The value of x should be in non negative number. If you are interested to know more about absolute value in mathematics, read the following post below:

## Facts about Absolute Value 1: the value of x

Let’s talk the value of x in detail. As I have stated before that x should be in non negative number. It means that |x| = -x for a negative x and |x| = x for a positive x. Even though you have –x, it is positive in absolute value. Don’t forget to pay attention that |0| = 0.

### Facts about Absolute Value 2: an example of absolute value

Based on the explanation above, we can derive the idea that an absolute value of 4 is 4. If you want to find out the absolute value of -4, it is also 4.

## Facts about Absolute Value 3: numbers in absolute value

The number that you can find out in absolute value is the one distance from zero.

### Facts about Absolute Value 4: absolute value in mathematics

Absolute value is one of the important topics in mathematics. You can also find it in other mathematical settings.  The ordered rings, quaternions, complex numbers, and vector spaces are defined using absolute value.
