This question is a little vague, but I'd like to ask total number of math symbols in TeX (or we can say amsmath?).
I cannot find information in ftp://ftp.ams.org/pub/tex/doc/amsmath/amsldoc.pdf document, and http://www.artofproblemsolving.com/Wiki/index.php/LaTeX:Symbols link gives approx. 290 kinds of math symbols.
I know that math symbols are treated as a sort of fonts in TeX, but does it have any information in common?
