This is a test of using MathJax in Blogger Note that enclosing math in single $'s does not work in the default setting for MathJax. However, you may use "∖(" and "∖)" for inline math and double dollar signs or "∖[" and "∖]" for displayed math. Examples: $(y+\sqrt z)^{-1}$ and sin2x2. And, a displayed equation is: 23
Another displayed equation is here:
∀x∃y(x≤y∧y≤x↔x=y).
To setup the MathJax capability, I added the following line to the HTML code, after the <head> command (as a single line, no line break):
<script src='http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML' type='text/javascript'/>
You can find more information from the MathJax website about this at http://www.mathjax.org/docs/1.1/start.html.
