this calculator uses shunting yard algorithm for calculating it can + - * / ^ and root numbers and make it all in correct order
the design was copied from apple calculator and modifiyed
F button turn formula mod and change some buttons
the main diffrence between apple and mine calculator is ability to change background and button color
in setting section you can change back ground colour to image change buttons background and text colours
you can change the calculate string colour and setting,return back buttons colours
also you can set it to default values
