    How to calculate

    You can use + − × ÷, brackets, ^ for powers, √ for square roots and % (50% is 0.5). Multiplication and division come before addition and subtraction. Both comma and point work as decimal separators, and Persian and Arabic digits are recognised. Everything is calculated in your browser and nothing is stored.
