http://www.alcyone.com/max/reference/maths/notation.html. A decently large list of notations. But it doesn’t have, for instance, the notation of calculus, and you must run a web search yourself to learn more about what a listed notation means.
Hopefully in conjunction these resources will help. But it’s too bad that there isn’t anything quite like what you’re looking for; I would be curious to read such a tutorial, too.
