Found a calculation that looks wrong, a broken link, or a number page that’s missing something it should have? That’s exactly what this form is for. This site’s entire value is being a source you can trust for a quick, correct answer, so a reported error gets fixed, not filed away. The math core behind every page is unit-tested, but a genuinely wrong computed value would be a serious bug — if you spot one, including a page and the specific number involved helps track it down fast. The same goes for a broken calculator, a guide that’s unclear, or a suggestion for a number, calculator, or guide that isn’t on the site yet but should be.

A few things worth including if you’re reporting a suspected error: the exact page URL or number involved, what you expected the answer to be, and how you checked it (by hand, with a different calculator, or a textbook reference). That context is usually enough to reproduce the issue against the math core directly and confirm whether it’s a genuine bug or a difference in convention (for example, some rounding edge cases have more than one defensible answer depending on which rounding rule is applied, and that’s worth knowing before assuming a page is simply wrong). Reports about broken links, unclear wording, or missing numbers are just as welcome as bug reports — this form isn’t only for errors.
