Adds two numbers the same way a computer does, with the AND, OR and NOT functions, which are in seperate sprites. This program uses a system similar to functions in C++, with variables for arguments and a variable for the value the function returns. Click the cat once and it will give the sum, and any more times will give the difference. The difference was an accident, I was planning on making it only addition. For some reason, this does not work online, Java or Flash. Please download. In case you can not download, hopefully you can figure out the sum or difference yourself.
