Pokročilá kalkulačka

An advanced calculator is a program that is able to calculate entire examples and formulas at once. It calculates by applying mathematical rules for precedence of operations, rules for counting with parentheses and with real numbers. It also has a correctness check.

In addition to arbitrary powers and square roots, it has other functions such as factorial, sine and cosine (cosine). The values of the last two functions are calculated in degrees.

The program is small in size and easy to use. It is useful, for example, in school, when you don't have to remember the intermediate results as on a regular calculator
