What to include in a useful message
Clear details make it easier to understand a question and reproduce a problem. If you are reporting a possible calculation issue, tell us which page you used, what values you entered, what answer appeared, and what answer or method you expected. A screenshot can help explain a layout issue, but remove personal or confidential information before attaching it.
- The calculator name or full page link.
- The inputs, selected options, and units.
- The result you saw and why it seems unexpected.
- Your device or browser if the issue is visual or mobile-specific.
Feedback about content and accessibility
Math Answer Hub is designed for clear reading, keyboard access, and comfortable use on phones as well as larger screens. Tell us if text is difficult to read, a control is hard to use, focus is unclear, or a result does not make sense with assistive technology. We value specific suggestions, including the device, browser, zoom level, and steps that led to the issue.
Calculator suggestions
If you would like to suggest a new calculator, describe the question it should answer and the audience it would help. Useful ideas include the common inputs, the expected formula, the preferred units, and any edge cases that matter. Requests are reviewed alongside maintenance and accuracy work, so a suggestion may not be added immediately, but every clear idea helps shape the library.
