Absolute Value Calculator
Find the absolute value |x| of a number.
Worth Knowing
Absolute value strips the sign from a number, returning its distance from zero on the number line, so both 7 and −7 have absolute value 7. That distance interpretation is why it appears everywhere a magnitude matters regardless of direction — measuring error, tolerance, or how far apart two values are. It also introduces a useful subtlety: the equation |x| = 5 has two solutions, since two points sit exactly five units from zero.
