What Is Absolute Value?
The absolute value of a number is its distance from zero on the number line.
Absolute value is always non-negative. It is represented by two vertical bars: |x|.
Absolute Value Formula
The absolute value of a number x is defined as:
|x| = x if x ≥ 0
|x| = −x if x < 0
- |x| = absolute value of x
- x = any real number
Example Calculation
Example: Find the absolute value of −5.
|−5| = 5
The distance from −5 to 0 is 5 units, so the absolute value is 5.
