Economics
I took AP Macroeconomics my Senior year, so I made some programs to help me do some repetitive homework more quickly.  They are all for the TI-83+ since I didn't have my 89 when I made these yet.  These are all integrated into each other and each component may be selected by the main program, "ECON."  I have not tried them out since my AP Macroeconomics class, so they may have errors.  If you do download and use the programs, please leave feedback, suggestions, and corrections on the "Contact Us" page.
 
For some reason, all zip files that I upload become corrupt when downloaded.  So, I uploaded the zip file containing all of the Economics programs to MediaFire, and the file is available for download here.
