Adding Latex to questions

Hello,

I would like to allow the user to enter Latex in their questions and answers

To get mathjax to compile Latex with the AskBug Theme, I’ve entered

function mathhead(){
echo <<<CSS
<script type=”text/x-mathjax-config”>
MathJax.Hub.Config({
tex2jax: {
inlineMath: [[”$”,”$”]]
}
});
</script>
<script type=”text/javascript”
src=”https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML-full”>
</script>
CSS;
}
add_action(‘wp_head’, ‘mathhead’);

in the functions.php file.

This works, but not all the way:

For some reason the character “\” is being removed when a user asks a question in the text editor. Why is this?
