Step by step
Get the absolute value of any number, or solve an absolute-value equation of the form |ax + b| = c.
Step by step
Get |x| for a number, or solve an absolute-value equation.
On the first tab, enter any number to get its absolute value — its distance from zero, always non-negative.
On the second tab, enter a, b and c for |ax + b| = c. The equation splits into two cases.
Each case is solved separately, giving up to two values of x. If c is negative there is no solution.
