Why doesn't this project utilize some variety of TeX typesetting to make the notation a bit more legible? Drupal has a number of modules that will do the trick.
I've emailed them to suggest MathJax, and to ask if they're intending to be running something. If they are, it's broken. If they're not, MathJax is superb.
No idea if they'll respond, but emailing them seemed more useful and productive than just complaining about it here.
