I suggest you take a course in math history. This is a pratical suggestion. There are community colleges perhaps near you. Register and take a course. If you are in USA, usually they are very cheap because it is funded by taxes. Typically it's 3 hours or so a week, adding homework it might be 10 per week, and last about 3 months. Try it. It's fun.

The above won't actually teach you much in htis issue. To get some level of basic knowledge on this, you'll have to have few years on inter-displinary study associated math history, math notations, markup langs, computer syntax, mathematical linguistics related to grammar n syntax...

Being a tech geeking hip creature, perhaps you'll never take the above advice. You'd rather immediate read some slashdot or google something and post profusely in online forums. For this, i recommend a few articles of my own:

• The Codification of Mathematics

http://xahlee.org/cmaci/notation/math_codify.html

• The TeX Pestilence

http://xahlee.org/cmaci/notation/TeX_pestilence.html

• The Problems of Traditional Math Notation

http://xahlee.org/cmaci/notation/trad_math_notation.html

• A Notation for Plane Geometry

http://xahlee.org/cmaci/notation/plane_geometry_notation.html

• The Concepts and Confusions of Prefix, Infix, Postfix and Fully Nested Notations

http://xahlee.org/UnixResource_dir/writ/notations.html

of course, i also have very technical and practical book length tutorials on emacs lisp, python, perl, java, javascript/html/css, php, povray. You can find them on my website.

Thanks.
