About This File
Aritm is a game that trains you in mental calculation. It only teaches what is necessary to know in order to calculate manually using pen and paper. It adapts and asks more about what you answered wrong before.
Aritm is written in pure BASIC v2 and uses X16 control codes for text and screen colors.
Future versions will probably support sound to signal wrong answers and perhaps larger text in game.
Aritm is available for many platforms including graphing calculators, Java phones, spread sheets, and common retro computers.
