Frequently asked questions
Can I use my keyboard with this calculator?
Yes. Number keys and the operator keys work as you would expect, Enter acts as equals, Backspace deletes the last digit, and Escape clears the calculator.
How do I clear just the last digit instead of everything?
Press Backspace to remove the last digit you typed. Escape (or the clear button) resets the whole calculation.
