Most attempts to communicate this notation to computers has been difficult at best, with MathML being much too complex for humans to actually write, and LaTeX often requiring much looking up of the various short cuts that been developed, particularly for beginners.
Here's an example of some LaTeX to produce a mathematical diagram.

Can you tell what the final output of this LaTeX will be? (See http://www.forkosh.com/mathtex.html for the answer)

Mathematics has also changed over time. Trying to read mathematics documents from Fermat's period would be rather hard today. In the 20th mathematics saw some pretty drastic changes in the way it's expressed (someone can correct me if I'm wrong on this). Check out this group who had some pretty big influence on how math is expressed today. http://en.wikipedia.org/wiki/Nicolas_Bourbaki
