How the Absolute Value Calculator Works
The absolute value of a number is its distance from zero on the number line, always zero or positive. It simply drops the sign: |−7| = 7 and |7| = 7. It answers “how far from zero?” regardless of direction.
Absolute value is used whenever the size of a difference matters but the direction doesn’t — error margins, distances and tolerances.
|x| = x if x ≥ 0, otherwise −x
Frequently Asked Questions
What is absolute value?
A number’s distance from zero, ignoring its sign. |−7| = 7.
What is the absolute value of a negative number?
Its positive counterpart — |−7| is 7.
Why is absolute value never negative?
Because it measures distance from zero, and distance can’t be negative.
