Casio fx-9750GIII Pink USB Graphing Calculator Python Geometry Calculus Physics

From an auction house that does Amazon returns, shelf pulls and overstock.  Turns on and displays various functions, but I have no idea what they do as its more complicated than I can understand!  I tested it on various basic math calculations.  Beyond that, most of the functions are beyond what I know.  Heck, I even had to youtube how to turn it off! lol (hit the shift key, then the off key because apparently just hitting the off key doesnt do it!).  Appears to be new or minimally used.

Loaded with tons of features - compare to TI-84 Plus graphing calculator (see last pic)

Please review all of the photos as they are part of the description and are of the actual item.  Photos will supersede any written descriptions in case I missed noting anything or made an error in what I did write, so please look closely and ask questions if in doubt.
