About MathSolverr
A free, fast and private math solver built to explain every step.
MathSolverr is a free online math solver. It turns a typed math problem into a clear answer with a step-by-step solution, so students, parents and teachers can check work and understand the method behind it.
What we believe
- Steps matter more than answers. Every tool explains the rule used at each step.
- Math help should be free. No account, no paywall on solutions, no daily limit.
- Privacy by design. The solver runs in your browser; your problems are not stored.
How MathSolverr calculates answers
Our tools use open-source symbolic math libraries to keep answers exact — fractions stay fractions and square roots stay square roots. When a problem has no exact closed form, the solver uses proven numerical methods (bisection for roots, Simpson’s rule for integrals) and clearly marks the result as approximate.
What you can solve
Equations and systems, inequalities, factoring and simplifying, fractions, percentages, derivatives, integrals, limits and graphs. See the full list on the math solver home page.
