I've got a fraction done this way in an org file:
\[
\frac{1}{(2^3)(5)}
\]
and I'd like to strike though or cancel the (5) part. The Latex method I've
found says do it this way:
...
\usepackage[makeroom]{cancel}
...
\[
\frac{1}{(2^3)\cancel{(5)}}
\]
But it's ignored and comes back verbatim. Of course +(5)+ doesn't work
either, again, coming back verbatim with the pluses. How can I do this?

Unless the \cancel{..} is not exported properly, this is a LaTeX
question. I think you will have better luck finding an answer if you
ask a community dedicated to LaTeX, e.g. TeX.SX.

Not sure what you tried, but it all works fine here for PDF export. The
following latex file works:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage[makeroom]{cancel}
\begin{document}
\[
\frac{1}{(2^3)\cancel{(5)}}
\]
\end{document}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---
and the following org file works as well:
--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage[makeroom]{cancel}
* Some math
\[
\frac{1}{(2^3)\cancel{(5)}}
\]
--8<---------------cut here---------------end--------------->8---
You must mean HTML export - MathJax apparently does not know about
\cancel. There is an extension mechanism:
https://docs.mathjax.org/en/latest/extension-writing.html
but that's as far as my knowledge extends. If you make it work, please
share.
Alternatively, you can use the (generally inferior) method of exporting
math as images - adding
#+OPTIONS: tex:imagemagick
works OK (assuming you have imagemagick installed of course).
There is also
#+OPTIONS: tex:dvipng
if you have dvipng instead.

It's actually simple - the documentation tells you exactly how to do it
using the cancel package as an example :-) - see the section "TeX and
LaTeX extensions" in
https://docs.mathjax.org/en/v2.5-latest/tex.html
All you need to do to incorporate that into org is to make it add the
script when you export. That is done by appending it to
org-html-mathjax-template:
--8<---------------cut here---------------start------------->8---
(setq org-html-mathjax-template (concat org-html-mathjax-template "
<script type=\"text/x-mathjax-config\">
MathJax.Hub.Register.StartupHook(\"TeX Jax Ready\",function () {
MathJax.Hub.Insert(MathJax.InputJax.TeX.Definitions.macros,{
cancel: [\"Extension\",\"cancel\"],
bcancel: [\"Extension\",\"cancel\"],
xcancel: [\"Extension\",\"cancel\"],
cancelto: [\"Extension\",\"cancel\"]
});
});
</script>
"))
--8<---------------cut here---------------end--------------->8---

Yes, Nick, I put it in my init and it worked. Amazing to me is how an elisp
concat just works, so I don't have to hack around with the
org-html-mathjax-template (Too close to Halloween). Thanks, everyone.

Put this in a #+latex_header line?

Sticking this after my initialization #+ stuff finally worked:
#+begin_html
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
TeX: {extensions: ["cancel.js"]},
tex2jax: {
inlineMath: [ ['$','$'], ['\\(','\\)'] ],
processEscapes: true
}
});
</script>
#+end_html
although I, the eternal beginner, don't quite understand other than MathJax
is pulling in this cancel.js and applying it. Got it off the MathJax Google
Group. I'm sure there's a better way to roll it into Emacs/org-mode
or org-html-mathjax-template?

Ah, it wasn't clear that you wanted export to HTML; the assumption I
made was you were exporting to LaTeX. I'm glad you found the solution.

Actually I spoke too soon. Putting
(setq org-html-mathjax-template (concat org-html-mathjax-template "
<script type=\"text/x-mathjax-config\">
MathJax.Hub.Register.StartupHook(\"TeX Jax Ready\",function () {
MathJax.Hub.Insert(MathJax.InputJax.TeX.Definitions.macros,{
cancel: [\"Extension\",\"cancel\"],
bcancel: [\"Extension\",\"cancel\"],
xcancel: [\"Extension\",\"cancel\"],
cancelto: [\"Extension\",\"cancel\"]
});
});
</script>
"))
in my init didn't fly when I rebooted, although it seemed to work before
when I stuck it in my init and did eval-buffer. Going back to
#+begin_html
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
TeX: {extensions: ["cancel.js"]},
tex2jax: {
inlineMath: [ ['$','$'], ['\\(','\\)'] ],
processEscapes: true
}
});
</script>
#+end_html
Would appreciate any advice on how to incorporate the \cancel code
into org-html-mathjax-template.

The code assumes that org-html-mathjax-template has been initialized
already, so either
(require 'ox-html)
beforehand or use eval-after-load:
(eval-after-load "ox-html"
(setq org-html-mathjax-template ....))
