We'd like to hear from you
Whether you spotted an issue with a calculator, have an idea for a new one, or just want to say hello — we're glad to hear from you.
What to include
If you're reporting a calculator issue, it helps to include: which calculator, what you entered, and what you expected to see. That's usually enough for us to track down the problem quickly.
