A small TI-BASIC program I wrote in my second semester at Riverdale High. There was another common Math program going around but it was about 5000 bytes (fairly big for a TI-83) and had alot of tools that Algebra II/Geomitry students didn't really need, and was lacking a few things that they did need (length of lines in 3 dimensions, volume and area of spheres and such,etc.). So I wrote GNU/Math.

It's about 2000 bytes smaller than the other program, and contains all of the features a Geomitry student may need. It's released under the GNU General Public License. However, I'm fixing it at the moment as I managed to break one of the menus last year, and I won't be giving it our to my tovarichy anytime soon.
