The modulus of a real number, n, is equal to

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|

Examples:

|-4|=4

|2.5|=2.5

|-100.1|=100.1

493 would be the correct answer
