# Adding LaTeX Support in Ghost

In the previous post we described the process of adding nice syntax highlighting in Ghost blog. We are missing one more important step to make a truly mathematically friendly - the LaTex support.

Thanks to MathJax this task is extremely easy to accomplish. In order to add MathJax to the blog we need to edit the `default.hbs`

file in your template (e.g. Casper) and put following code between `<body>`

and `<\body>`

tags

```
{{! Mathjax configuration}}
<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']],
displayMath: [['$$','$$'], ['\[','\]']]}
});
</script>
```

Simple. Let's see this in action. This code `$$\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi}{6}$$`

will yield

$$\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}$$

The nice feature is that if you right-click on the equation, you can select to display the equation in TeX or MathML code.

In future posts we will use both syntax higlighting and LaTeX extensively.
