• The absolute value |x| is the distance from x to 0 on the number line
• |x| = x if x ≥ 0 (positive numbers stay the same)
• |x| = -x if x < 0 (negative numbers become positive)
• |0| = 0 (zero’s absolute value is zero)
Examples: |5| = 5, |-5| = 5, |0| = 0
In mathematics, the absolute value of a number represents its distance from zero on the number line, regardless of direction. It is a fundamental concept used in algebra, calculus, finance, and data analysis. The Absolute Value Calculator makes it quick and easy to find the absolute value of any number, whether positive, negative, or decimal.
This tool is ideal for students, teachers, engineers, and anyone working with numbers who needs accurate results in seconds.
What is Absolute Value?
The absolute value of a number is its magnitude without considering its sign. It is denoted by vertical bars:
|x|
- If x is positive or zero, |x| = x
- If x is negative, |x| = -x
Examples:
- |7| = 7
- |-5| = 5
- |0| = 0
Absolute values are used in measuring distances, evaluating errors, analyzing financial data, and solving equations.
