I am having trouble getting both html and latex (to pdf) to render plain math latex environments.
For html to work, equation environments have to be nested inside $...$ but then that doesn't work for latex.
I think this issue was fixed in Pandoc 1.XX?, but I see the issue returning when I use 2.2.
Details below. Thanks for your help, and thanks for Pandoc!

Typesetting math
-------------------------------------------------------------------------------
You can do latex inline like this:
Euler's formula is remarkable: $e^{i\pi} + 1 = 0$.
Euler's formula is remarkable: $e^{i\pi} + 1 = 0$.
You can use `$$` to make an equation block like this:
$$ \frac{\partial \rho}{\partial t} + \nabla \cdot \vec{j} = 0 \,. \label{eq:continuity} $$
$$ \frac{\partial \rho}{\partial t} + \nabla \cdot \vec{j} = 0 \,. \label{eq:continuity} $$
The latex equation environment can be used directly.
Stokes' theorem is pretty cool:
\begin{equation} \label{eq:stokes}
\int_{\partial\Omega} \omega = \int_{\Omega} \mathrm{d}\omega \,.
\end{equation}
\begin{equation} \label{eq:stokes}
\int_{\partial\Omega} \omega = \int_{\Omega} \mathrm{d}\omega \,.
\end{equation}
You can also refer to labeled equations, such as [@eq:stokes],
with the syntax:
... such as [@eq:stokes],
The `align` environment can also be used.
Maxwell's equations, [@eq:maxwell], are also tough to beat:
\begin{align}
\nabla \cdot \vec{E} &= \rho \nonumber \\
\nabla \cdot \vec{B} &= 0 \nonumber \\
\nabla \times \vec{E} &= - \frac{\partial \vec{B}}{\partial t} \label{eq:maxwell} \\
\nabla \times \vec{B} &= \vec{j} + \frac{\partial \vec{E}}{\partial t} \nonumber \,.
\end{align}
\begin{align}
\nabla \cdot \vec{E} &= \rho \nonumber \\
\nabla \cdot \vec{B} &= 0 \nonumber \\
\nabla \times \vec{E} &= - \frac{\partial \vec{B}}{\partial t} \label{eq:maxwell} \\
\nabla \times \vec{B} &= \vec{j} + \frac{\partial \vec{E}}{\partial t} \nonumber \,.
\end{align}
Mathjax
-------------------------------------------------------------------------------
When doing md $\rightarrow$ tex $\rightarrow$ pdf, LaTeX takes care of the math,
but to render the math in html, we use [MathJax](https://www.mathjax.org/).
Our html template includes the following code
to ask MathJax to render it and number the equations:
<!--- MathJax stuff -->
<script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.4/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({ TeX: { equationNumbers: {autoNumber: "all"} } });
</script>
Please note there are "naked" latex environments: \begin{equation}... and \begin{align}.
Things were working fine with an older version of pandoc.
Then if I switch to 2.2:
brew switch pandoc 2.2
Cleaning /usr/local/Cellar/pandoc/1.19.2.4
Cleaning /usr/local/Cellar/pandoc/2.2
5 links created for /usr/local/Cellar/pandoc/2.2
And then run pandoc -t html --standalone --mathjax min.md, I get:
[WARNING] Could not convert TeX math ' \frac{\partial \rho}{\partial t} + \nabla \cdot \vec{j} = 0 \,. \label{eq:continuity} ', rendering as TeX
[WARNING] This document format requires a nonempty <title> element.
Please specify either 'title' or 'pagetitle' in the metadata.
