No paywall. No account. No catch.
Every tool on this site is free. Not free-with-a-premium-tier. Not free-until-you-hit-a-limit. Just free.
Our commitments to you
Three core guarantees that govern how this site is operated.
Self-Funded & Independent
mathsolvers.io is built and maintained by its founders. We pay for the hosting, domain, and infrastructure ourselves. There are no investors, no venture capital, and no pressure to monetize or compromise the learning experience.
Your Data Stays on Your Device
We never sell, share, or trade personal data. We don't collect personal data in the first place. Your calculation history is saved solely in your browser's local storage and never transmitted to our servers.
Zero Barriers to Learning
No account creation, no passwords to remember, no credit cards, and no marketing emails. You get straight to the calculation and step-by-step working the moment the page loads.
What will always be free
Every feature on mathsolvers.io is open to every student, teacher, and parent.
All calculators & converters
Every tool includes the full step-by-step working and algebraic methods — never just the final answer.
The Three Lenses breakdowns
Dedicated guides for students (Learn it), teachers (Teach it), and parents helping at home (Understand it).
Interactive grids & reference charts
Times tables, addition grids, prime number tables, and exact trig ratios with ink-friendly print layouts.
Calculation history & replaying
Review previous calculations and jump back into past working anytime on your device.
The Library Principle
We built this because we needed it — as parents who struggled to help our daughter with her homework because the existing tools were either gated behind subscriptions or showed only answers without explanation.
Good maths tools should be as free and accessible as a public library. A student should not need a credit card to understand how compound interest works, or to see step-by-step working for simultaneous equations. When you put a paywall in front of educational foundational tools, you decide that only some students deserve to understand.
Help spread the word
If mathsolvers.io has helped you, your children, or your students — tell a friend, colleague, or teacher. That is the greatest support you can give this project.
