# Can anybody recommend a comprehensive source for understanding mathematical notations?

I foten struggle with understanding some of the mathematics written down in papers. This stuggle is often due to notation used. Therefore, I was wondering whether somebody is aware of a resource that explains how read the formulas. I am talking about signs like: ∑, y||2 and some others.
