You might of heard of that ti89 scam, but that's a cger ok. This program made 100% by me is where it's at. Spoiler Ok let's be honest. Ricky did all of the coding and half the gui. I added the exponents function though(by copying and pasting rickys code!). I watched in teamviewer though :tehe: and umm corrected his mistakes?? Lol yeah none. This is a pro calculator. If you take the achetuer ultime and a working flare scoresender, raise them to the infinity power, this program is still OVER 9000 times better. It has been rumored that nasa has requested this to calculator aeronautical things.
