I already tried this method, but still can't get it done, but thanks for advice.
What "method" did you try? Program your owns? Search the forum for solutions?
What did you do so far?
Front panel: Did you place all the buttons you need? (numbers, delimiter, operations, etc.)
Block Diagram: Do you have a toplevel while loop? Some way to poll the buttons (events, polling)? Did you decide what the states are? Do you have a method to maintain a stack? Do you have a method to accumulate numbers from consecutive numeric buttons? Are you familiar with RPN inputs (Hey, no equal button!)? Etc.
What part caused you problems?
Thank you for posting something like this
