How do you type the dollar sign when you have mathjax installed?

Question

So in Jekyll and Markdown, I can\'t type $ or its HTML equivalent code, and not \\$ nor $\\$$. How should I type the dollar sign?

Answer 1

I used mathjax's dollar symbol in that paragraph. It works.

Answer 2

Enable processEscapes:

MathJax.Hub.Config({
  tex2jax: {
    inlineMath: [['$','$'], ['\\(','\\)']],
    processEscapes: true
  }
});

Then you can simply use \$ to get a plain $.

Answer 3

To prevent MathJax from using the dollar sign as a delimiter, you can put it in a span, like so:

<span>$</span>

Alternatively, you can enable processEscapes and then you can use the backslash escape \$ for the dollar sign.
