Absolute value calculator
Calculate absolute values, solve absolute value equations |ax+b| = c, and graph absolute value functions.
Expression
Absolute value
|x| is the distance from x to zero on the number line. Always non-negative.
Rules
|x| = x if x ≥ 0, |x| = −x if x < 0. |5| = 5. |−7| = 7. |0| = 0.
Properties
|ab| = |a|·|b|. |a/b| = |a|/|b|. |a+b| ≤ |a|+|b| (triangle inequality).
