Contact

Questions, corrections, or a calculator you wish existed? Email us at contact@mathbench.com.

We especially want to hear about:

• Errors. If a result doesn't match a hand calculation or a trusted reference, include the inputs you used and we'll investigate.
• Missing tools. Tell us what you were trying to calculate. The backlog is driven by requests.
• Outdated figures. Tax rates and material specs change. If you spot a stale number, flag it.

We aim to reply within a few business days.
