Just click the flag, and type in what it asks you to. PROTIP: Use the first two decimal points when writing out the results, remember to round!
I made this all myself. A prototype at the moment, I will add more features as time goes on. PLANNED FEATURES: - A help panel, to tell you how to get the functions and what they do exactly. - Music. - ALL THE CLICKY BUTTONS. - A teaching panel, to help teach you how to do the calculations. - Better graphics and a 're-skinnable' interface.
