Frequently Asked Questions (FAQ)

How does the percentage (%) button work?

The percentage button can be used in calculations. For example, to add a 15% tip to a $50 bill, you could type `50 + 15 %`. The calculator would first evaluate 15% of 50 (which is 7.5), and then add it to 50 for a total of 57.5.

Can I use my keyboard?

Yes! The calculator is fully keyboard accessible. You can use number keys, operators (+, -, *, /), Enter for equals, Backspace for delete, and Escape for all clear.

What does the history panel do?

The history panel on the right side of the calculator automatically records each completed calculation (e.g., "10 + 5 = 15"). This allows you to review your past work without having to re-enter anything.

How do I copy a result?

You can use the "Copy Result" button to copy the currently displayed value or the result of the last calculation in your history to your clipboard.
