Frequently asked questions

Does it follow the order of operations?

Yes. Multiplication and division are done before addition and subtraction, so 2 + 3 × 4 = 14. Use the scientific calculator if you need brackets on the keypad, or type them with your keyboard.

How do I add a percentage to a number?

Type the number, then + and the percentage followed by %. For example 80 + 15% gives 92.
