# How to make Obsidian and Jekyll equations compatible

# TL;DR

Set `processEscapes`

to `False`

or remove it from `tax`

dictionary

```
<script>
MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']],
},
svg: {
fontCache: 'global'
}
};
</script>
<script type="text/javascript" id="MathJax-script" async
src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js">
</script>
```

# What was not working

I’ve tried to write blog posts using Obsidian for my Jekyll website. The issue was the Mathjax version I was using didn’t recognize single dollar sign for inline equations.

I was using this Mathjax setup taken from the documentation:

```
<script>
MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']],
processEscapes: true
},
svg: {
fontCache: 'global'
}
};
</script>
<script type="text/javascript" id="MathJax-script" async
src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js">
</script>
```

But the \$ signs in my markdown was displaying as \$ in the rendered HTML. Some of the related answers mentioned the issue of markdown + Mathjax processing order.

I’ve tried different `inlineMath`

options, but at the end downgrading to `2.x`

version solved the problem.

```
<script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.6/MathJax.js?config=TeX-MML-AM_CHTML">
</script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
extensions: ["tex2jax.js"],
jax: ["input/TeX", "output/HTML-CSS"],
tex2jax: {
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
},
"HTML-CSS": { availableFonts: ["TeX"] }
});
</script>
```

However after trying with options later, turns out just removing `processEscapes`

seem to solve the problem.
