Unlike other global objects the Math object has no constructor. You may sometimes see exponents expressed using the older Mathpow method which works in a very similar way. This is more efficient and accessible than using images.
Currently the best way of including equations in HTML documents is to first write the document in LaTeX and then use the latex2html filter to create the corresponding HTML document together with the equations as a number of bitmap files 1.
Equation numbers are pretty easy to achieve by wrapping an expression in the middle cell of a table of width 100 and putting the equation number in the rightmost cell with text-align set to right. Example - the integral from a to b of fx over 1x _a_bfx1x dx which can be rendered on a fixed pitch text-only medium as. For the complicated equations. So I started looking out for a different solution and found this awesome Javascript library called MathJax which displays Math equations using HTML CSS and SVGs.
