Contact
We would like to hear from you. Whether you spotted a mistake, have a question, or want a calculator we do not offer yet, this page is the way to reach us.
Send Us a Message
The fastest way to reach us is the contact form. It comes straight to us, and it is the best channel for corrections, questions about how a tool works, privacy questions, and requests for new tools or worksheets.
What to Reach Out About
- Corrections. A wrong result, a broken calculator, or a mistake in an answer key. These are our top priority.
- Requests. A calculator, converter, worksheet, or topic you wish we covered. Suggestions genuinely shape what we build next.
- Questions. How a particular tool works, or how it arrives at its answer.
- Privacy. Anything about the data practices described in our privacy policy.
Reporting a Correction
If you find a calculator issue or an answer key mistake, please include the page URL and, where it applies, the specific problem number or the exact numbers you entered. That detail lets us reproduce the problem and fix it quickly. Accuracy matters to us, so these reports are always welcome.
Response Times
Simple Number Tools is run by a small team, so replies are not instant, but we read every message and work through corrections as fast as we can. You may not receive a personal reply to every note, but rest assured it has been read.
Children and Contact
If you are under 13, please ask a parent, guardian, or teacher to fill out the form for you. Please do not send your full name, school name, home address, phone number, or other personal information.
