All right, it's time for everyone's favorite post: the list of posts that would benefit from MathJax! The Stack Exchange team looks for posts that would benefit by having MathJax (they want to make sure it's actually needed), so let's make a list of such posts. As this is a community wiki, feel free to edit in posts that would benefit, but are missing. the ...

Yes And, the default escape-sequence for MathJax on SE is to use a $, like $log(n)$ .... Should this be changed (like it is on some other Stack Exchange Sites) to \$ (as in \$log(n)\$ ) ? If the site uses the $ often in regular question text, then it can cause problems with the page parsing. Will it be common here to have $100 currency values? Or programs ...

The escape sequence should be $. $ is what people who already know (La)TeX use. Even more importantly, $ is what people who already know how to write math on Stack Exchange use — it's what Mathematics SE uses, and it's what all the MathJax documentation on Stack Exchange (mostly on Math meta) uses. Even the upstream MathJax documentation uses $ in its ...

It was interpreted as Markdown for an ordered list with one list item numbered 110101. I can replicate this below as such: List? Ha Note that setting the start number like this isn't a typical Markdown feature. If you really feel the need to format a post that way, this can be circumvented/prevented by1: Inserting a backslash (\) between the number and ...

I didn't even think it would even be an issue, so I didn't post earlier, but… The escape sequence should be $. $ is what people who already know (La)TeX use. Even more importantly, $ is what people who already know how to write math on Stack Exchange use — it's what Mathematics SE uses, and it's what all the MathJax documentation on Stack Exchange (mostly ...

Unfortunately, this is not a bug but an intended feature, supposedly an "improvement", recently rolled out across the entire SE network: Some improvements to blockquotes You can support this proposal if you want it changed back: Please revert the quote background from white to yellow

It's not part of Markdown; it's one of the few HTML tags that are also supported on Stack Exchange. The tag defines a keyboard input. The tag is used when it is necessary to display a text that the user should enter into the keyboard (for any number of reasons). (source: w3docs.com) It doesn't really have a purpose on Puzzling Stack Exchange, it's more ...

Riddle me this: \$ \begin{array}{l|l|l} \text{Site} & \text{Puzzling} & \TeX - \LaTeX & \text{Math} \\ \hline \text{MathJax} & \text{True} & \text{False} & \text{True} \\ \text{Delimiter} & \backslash\text{\$} & \text{NULL} & \text{\$} \\ \end{array} \$

SPOILER BULLETS Syntax is >! <ul> <li> tag</li> >!<p>An unordered list:</p> >!<ul> >! <li>Coffee</li> >! <li>Tea</li> >! <li>Milk</li> >!</ul>

I fixed it for you by adding <P> tags.

This is a known bug If you have text right above or below the table, the preview renders the table markdown as a table. But after you save the post, the table is not rendered and just shows the markdown code. The rest of that answer is a demonstration of the bug.

It may look like a button to you, but as you've seen it's not clickable and should not be used to try to represent a button in a user interface. It's supposed to look like a keyboard key. So you might tell someone to press Ctrl F to do something. Using it because it's visually interesting, has a grey background, draws a box around your text etc is considered ...

Even if it isn't necessary, it will be very nice. The symbol I may miss most is the times sign-in my answer here about sudoku, I find 9 x 9 ugly, while $9 \times 9$ is much more elegant. Yes, you can read the former but lots of puzzles involve grids and it is nice to talk about the dimension this way.
