A language for describing mathematical expressions.

Spec | Playground

## Overview Universal Language for Mathematics (ULM) is a language for describing both the semantics and presentation of mathematical expressions. ⚠️ WIP ⚠️ A ULM [AST](https://en.wikipedia.org/wiki/Abstract_syntax_tree) might look something like this: ```yaml type: root value: type: multiply left: type: int value: 4 right: type: int value: 7 ``` Which might be presented like this: ``` 4 × 7 ``` We could also layer on some information to explicitly define how it should be presented: ```yaml type: root value: type: multiply style: dot left: type: int value: 4 right: type: int value: 7 ``` Which might be presented like this: ``` 4 • 7 ``` Alternatively, it could be presented in words: ``` four multiplied by seven ``` It could even present in another language: ``` cuatro multiplicados por siete ``` It might even be presented graphically: ``` 🦄🦄🦄🦄 🦄🦄🦄🦄 🦄🦄🦄🦄 🦄🦄🦄🦄 🦄🦄🦄🦄 🦄🦄🦄🦄 🦄🦄🦄🦄 ```
