Corrections

If a number, a zone or a result looks wrong, tell us. Write to hello@gardenbedmath.com with the page address and what you expected to see. A link to the source you are using helps.

What happens next

• We check the figure against its original source.
• If the page is wrong, we fix it, add a test case for the error to the calculator, and update the page date.
• If a source has changed its figure, we update the source record and the date checked, and every page that uses it changes on the next release.
