How do I create mathematical expressions for display with MathJax?
MathJax is a method to display mathematics. It is not an authoring environment, and so you will need another program to create mathematical expressions. The most common languages for mathematics on the computer are (La)TeX and MathML, and there are many authoring tools for these languages. MathJax is compatible with both MathML and (La)TeX. LaTeX code is essentially plain text, and so you do not need a special program to write LaTeX code (although complete authoring environments exist). If you are not familiar with LaTeX, you will need some determination to learn and master the language due to its specialized nature and rich vocabulary of symbols. There are various good tutorials on the net, and there is not a one-size-fits-all best one. A good starting point is the TeX User Group, or have a look at the LaTeX Wiki book. MathML is an XML-based web format for mathematical expressions. MathML3, the latest version, has been an official W3C recommendation since October 2010. MathML is widel
