Is encountering function notation and the symbol for the set of real numbers all that different from encountering unfamiliar vocabulary? It is slightly harder to Google for notation, but otherwise I do not see a major difference.
In the Wikipedia page you linked, I immediately encounter several terms that I do not know the meaning of. I must either click through or search separately to fill in my own gaps.
Your criticism is not totally disagreeable, but we have to wonder where to draw the line. Is a "Hacker's Guide to Numerical Analysis" obligated to hold your hand all the way through basic notation? The notation that you mention in your comment are the "Hello world" of mathematics.
