### MathJax - displaying LaTeX math in Blogger

Ok, so I apparently either forgot to post this or it somehow got erased. I think I just forgot. Anyways, this is what I found to use to display LaTeX math in my Blogger post. MathJax also displays MathML. You can install a javascript into you Blogger template or install MathJax to work from your own server.

I did the install from the CDN. I posted this Javascript into my Blogger template. I think you could do it for just post with LaTeX math displays, but I figured this would be the easiest way to do it. It may pose problems later, but we'll see.
<script type="text/javascript"

</script>


My screen shot of where I pasted the Javascript in my Blogger template. Just go to the Edit HTML tab. I pasted it near the top of the template and it works! (At least for me and my template.)

To insert inline equations you must use:
 $$...$$
To insert a set off "mathdisplay" equations you can use:
 $$$...$$$, $$$$...$$$$, $$...$$
or any other math environment such as:
 \begin{align}...\end{align}
