Concepts
Absolute value is the distance of a number from zero on a number line. It is a measure of the magnitude of a number, without regard to its sign. The absolute value of a number can be positive, negative, or zero.
Formula
The absolute value of a number is denoted by the vertical bars | on either side of the number. The absolute value of a number can be calculated using the following formula:
|x| = x if x >= 0
|x| = -x if x < 0
where x is any number.
For example, the absolute value of 5 is 5, because 5 is greater than or equal to 0. The absolute value of -5 is also 5, because -5 is less than 0.
Benefits
