The absolute value
Step-by-step explanation:
we know that
The modulus of a real number, is equal to the absolute value of the real number
so
The modulus of a positive number is simply the number and the modulus of a negative number is found by ignoring the minus sign.
Then
modulus of n is always positive number .such that n belongs to real number R.
Modules of n is denoted by |n|
<u><em>Examples:
</em></u>
|-4|=4
|2.5|=2.5
|-100.1|=100.1
