Frequently asked questions
What does absolute value mean?
It's a number's distance from zero on the number line, regardless of direction — so both -7.5 and 7.5 have an absolute value of 7.5.
Is the absolute value of a positive number different from the number itself?
No — a positive number (or zero) equals its own absolute value; only negative numbers change (they become positive).
Where is absolute value used?
It's commonly used to measure error or distance regardless of direction, such as in percent error calculations or when comparing how far a value is from a target regardless of whether it's above or below.
