Frequently asked questions
What can I use the Basic Calculator for?
Use it for everyday arithmetic: adding totals, subtracting costs, multiplying quantities, dividing amounts, checking percentages, and copying quick answers.
How does the percent button work?

Can I use keyboard shortcuts?
Yes. Use the number keys, +, -, *, /, x, Enter or =, decimal point, percent, Backspace, Escape, and Delete.
Is my calculation history private?
Yes. The history is only kept in the current browser tab while you use the page. It is not sent to a server.
