// Please enter a detailed description of the issue // Description of the issue:

Some math equations containing tow or more _{} do not render correctly.

$$f_{y}(x)$$ ok $$f_{y}(x) g_{y}(x)$$ does not render, which is acceptable syntax in MathJax.

// Please enter a list of steps required to reproduce the issue // Steps to reproduce:

1. Type $$f_y(x) g_y(x)$$
   
2. Change to $$f_{y}(x) g_{y}(x)$$
   
3. Try some complex formular from MathJax.org, such as
   $$\sigma = \sqrt{ \frac{1}{N} \sum_{i=1}^N (x_i -\mu)^2}$$ not working.
4. Remove some part $$\sigma = \sqrt{ \frac{1}{N} \sum_{i=1}^N}$$

   It looks like you left out all of the configuration info I would need to diagnose the issue.

   My configuration is as followed. Sorry for the inconvenience.
   It seems some underscores in between $$ are parsed as and carets as ^.

   Do you have the same issue using the MultiMarkdown processor
   (Preferences->Processor)?

   Switching to MultiMarkdown processor solves the problem. Thank you!
   There is just a tiny issue with large square root symbol. No glitch if KaTeX is used instead of MathJax.

   Glad to hear that's a good fix for you. I'm afraid the GFM processor
   doesn't avoid rendering underscores as italics inside of equations as
   well as it should.

   I'm very inexperienced with MathJax (and KaTeX), honestly, so I can't
   offer a lot of troubleshooting with the smaller quirks. If there's
   something you think Marked's version of Mathjax is doing wrong that it
   shouldn't be, though, let me know. If it works elsewhere but not in
   Marked, I can look into why that would be.
