A little experiment to implement some basic arithmetic using only the Typescript type system. The Typescript type system is known to be turing complete, so why not?
The project has a package.json but the only dependency is the typescript compiler. If you have that system wide, you may not even need to install it.
The math.ts file is written in a literate programming style, so you should just read through that file from the top to bottom to learn how it all works.
