An annoying aspect of having mathematics training: if you want to learn about a new topic, X, you'd like to read "X made easy", but most people's idea of "X made easy" is to present X with as much mathematics removed as possible, and that's what most tutorials out there look like to me.

@dpiponi are there different types of "documentation" for math? I've found the division into 4 kinds of documentation for software tremendously useful. I recommend it to everyone who writes software documentation because it makes life easier: https://documentation.divio.com/
