About SolvCalc

SolvCalc is a small independent project that makes maths easier to check and easier to understand. We build free online calculators that show their working, and we write short study guides that explain the method behind each topic in everyday language.

What we believe

• The working matters. An answer you cannot explain is not much use in an exam. Every calculator here shows its steps.
• Free should mean free. No sign-up, no account and no limit on how often you use a tool.
• Privacy by default. Calculations run in your browser. What you type into a calculator is not sent to us.
• Plain English. If a guide needs a glossary to be understood, we have not done our job.

How we make things

Each calculator is tested against worked examples that we check by hand before it goes live. Our guides are written to be read in a few minutes, with examples you can reproduce, and we update them when we spot a mistake or a clearer way to explain something.

How the site is funded

SolvCalc is supported by advertising shown on some pages. Ads help cover hosting and let us keep the tools free. We try to keep them out of the way of the calculators themselves.
