If you have always wanted to use math symbols in html, go to Irrep for an indepth tutorial.
Paste the code below after the first <head> tag of your layout
<script src='http://cdn.mathjax.org/mathjax/latest/MathJax.js' type='text/javascript'> MathJax.Hub.Config({ HTML: ["input/TeX","output/HTML-CSS"], TeX: { extensions: ["AMSmath.js","AMSsymbols.js"], equationNumbers: { autoNumber: "AMS" } }, extensions: ["tex2jax.js"], jax: ["input/TeX","output/HTML-CSS"], tex2jax: { inlineMath: [ ['$','$'], ["\\(","\\)"] ], displayMath: [ ['$$','$$'], ["\\[","\\]"] ], processEscapes: true }, "HTML-CSS": { availableFonts: ["TeX"], linebreaks: { automatic: true } } }); </script>
Take this exampleThe expression to type when you want to display the sqaure root of a fraction a/b is \sqrt{\frac{a}{b}}. To make sure that the exression is transformed by MathJax, you have to enclose it in $ $ like $expression$ and here is how it looks $\sqrt{\frac{a}{b}}$.
Here is trigonometric identity expression \cos^2\theta + \sin^2\theta=1 which would display $\cos^2\theta + \sin^2\theta=1$

\[\sum_{k=1}^n k = \frac{n(n+1)}{2}\]
\[\sqrt{\frac{a}{b}}\]
