This was my 7th grade (2012) math project. The assignment was 'Make a game to demonstrate operations with positive and negative integers', and this is what I made. I made this program in BASIC (a very old language). I built this program for the YaBasic interpreter, which you need to run this program. This made my teacher angry. I recently added indentations to the code, and I tried to use gotos to this is pretty much a compilation of many bad programming practices. I'm amazed that the code actually works [as often as it does]. I would never recommend BASIC to anyone
