This is a reverse polish notation calculator which usess post-notation and operands are written after operators. Notation does not use parethensis resulting in faster writting of complex computations.

Operators and operands have to be separeted by comma (,) and number of operators has to be larger by one compared to number of operands. In case user enters anything other than operands (+,-,*,/) or operators ([0-9]) error will be displayed. In case user does not enter anything in the field and pressess Compute button error will be displayed.
