Straight answers

Calculator questions.

How does the percentage button work?

By itself, % divides the displayed number by 100. During addition or subtraction, it treats the percentage as a portion of the first number: 200 + 10% gives 220.

Can I use my keyboard?

Yes. Use the number keys, decimal point, +, −, *, /, %, Enter or =, Backspace, and Escape to clear.

Does HandyPebble save what I calculate?

No. There is no account or saved calculation tape. The calculator runs in your browser and the current calculation disappears when the page is refreshed or closed.

Is this a scientific or financial calculator?

No. This one is intentionally built for everyday arithmetic. It should not replace specialized financial, tax, engineering, or medical software.
