MathJax shouldn't be used for non-maths purposes like fancy italics ... I partly agree with your post. Sometimes MathJax is used just to make something look fancy even when it's nothing to do with mathematical notation, e.g. $fancy\;italic\;fonts$ which as you say render terribly. ... but it SHOULD be used for maths notation, even when other things would ...

How to ignore tags You can add the riddle to your ignored tags. You can then choose between filtering them out (not showing them at all), or just greying them out. You can do this at Your preferences page. (note: this uses a special link, that makes sure that it links to the preference page of the user clicking it. You can make such link by using current ...

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 ...

I think @Rand al'Thor answer contains a valid argumentation about the "how mathematics should look" part but I have something to say regarding the dyslectics and screen readers part. MathJax takes some time to load, that's true, but it is loaded asynchronously so most users will barely notice the delay. I don't think that screen reader users are ...

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 ...

How to list puzzles and filter out unwanted categories To find all puzzle questions except those containing a specific tag, use the search field and enter is:q -[riddle] This will give you all entries which are questions but do not contain the riddle tag. Unfortunately, search will by default show you the list "by relevenace" so you have to click ...

Formatting spoilers You can insert a single-line spoiler easily by using >! at the beginning of any line: >! This is a spoiler By default, spoilers on subsequent lines are merged into a single paragraph. To insert a line break, add two spaces at the end of a line: >! This is the first line <-- two spaces >! This is the second line ...

How "Favorites" can be used Use "favorites" to keep track of unsolved puzzles that: you're working on you want to know the answer to you'd like to up/down vote, but want to wait until you see the solution Once you've added stars to puzzles you're interested in, you can view them on your user page (under Activity, Favorites). Better yet, you can sort by ...

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 ...

$%Is it possible to have an entirely blank post?$

Both delimiters ($ and \$) are now active, until existing comments and posts can be cleaned up to use $ only. Update Jun 21 2014: All 37 comments with the old syntax have been edited (thanks Tim Stone for updating the Data Explorer with Puzzling!). All that's left is questions and answers now. There are only 70 of them, and you can help edit! (Please only ...

How to notify a question author of a modified answer post Use @UserName in a comment (of the edited answer) to automatically send the user UserName a notification (containing the comment). When you type @ in a comment, other authors of this post are suggested by the auto-complete. You can also type any user-name, not only the suggested ones. In particular,...

Simply include the MathJax between dollar signs ($), like so: blah blah $\sum_{x=0}^{100}(x)$ blah blah blah $\sum_{x=0}^{100}(x)$ blah If you want the MathJax to be displayed as its own block, rather than inline, use two dollar signs: $$\sum_{x=0}^{100}(x)$$ $$\sum_{x=0}^{100}(x)$$ For a comprehensive tutorial, see this post on meta.Mathematics.

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} \$

Here is a slightly better version, but I think it needs work before being made into a macro for the site - it has unnecessary spacing, both within cells and between blocks, so it spills over the sidebar (at least on my browser), maybe someone else can work out how to avoid that while still keeping everything aligned? First a sudoku with relevant pencil ...

How to link to questions and specific answers You can link to any question by just pasting the URL to it directly. The display code will automatically show the title of that question as a link. example: In the text field of a question or answer you can type: https://puzzling.meta.stackexchange.com/questions/4894/useful-tips-tricks and it will be ...

How do I get some fancy symbol/font/format ? Puzzling Stack Exchange supports MathJax You can find lots of examples!

Check out my answer for: All neighbor sum is 0 on a chessboard to see how to spoiler long MathJax.

\$\mbox{math}\$ renders as \$\mbox{math}\$ $$\mbox{math}$$ renders as $$\mbox{math}$$ In Chrome, they both look correct to me. Are you sure it isn't just a typo?

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.
