I use WP QuickLaTeX by Pavel Holoborodko in some of my articles to include mathematical formulas.
Now it can be an issue that the „$“-sign, that marks the beginning of a formula, is used as dollar sign.
This can be achieved by using [latexpage] in the beginning of the page. Sometimes it is desirable, to apply this only to part of the page. This is achieved using [latexregion].
The following
$ this is a dollar sign
[latexregion]
And this is a full line formular
$$a^2+b^2=c^2$$
And this is an inline formula $a^2+b^2=c^2$. With more stuff...
[/latexregion]
And here dollar signs $$$$ are dollar signs again.
results in:
$ this is a dollar sign
And this is a full line formular
![\[a^2+b^2=c^2\]](https://brodowsky.it-sky.net/wp-content/ql-cache/quicklatex.com-5961b823500d85bcc83df69617a77e33_l3.svg "Rendered by QuickLaTeX.com")
And this is an inline formula

And yes, to show the

[/latexregion]
above, I had to actually type
[latexregion]

Let’s stop the recursion here…
