Frequently asked questions
Can I use my keyboard?
Yes: type digits and operators directly. Enter or = calculates, Backspace deletes, Esc clears.
What does the % key do?
With + or − it applies a percentage of the first number (500 + 10 % = 550). On its own, or with × and ÷, it divides the number by 100.
