How to write symbol in math mode in LaTeX/MathJax?

How can we insert the symbol in math mode for LaTeX and MathJax without loading any package that is required to achieve this symbol?
I tried
documentclass{article}
usepackage{amsmath}
begin{document}
$$
end{document}
but the program gives errors, also with ${}$, text{} etc. fails. In MathJax I use $$ and it produces error.
The context of the problem is I want to represent the (missing) symbol inside a formula (not in SE). The solution is add that symbol, so I want to alert the user "Hey, you forgot to add $$ in ${1,2,3}$. It should be ${1,2,3}$" (of course the site does not have single quotes (`)).
Thanks!!

Reading your comment to Henri's answer, I think it would be better to add to your question why you want to use a backslash character in math mode. Displaying escaped braces in math mode seems really uncommon to me, so perhaps there is a completely different but better solution to your actual problem (I suspect it has to do with displaying source code)

@manooooh I would use a code block in HTML (or whatever output format you're using): anything except a LaTeX/MathJax formula (because you want to show the literal raw text that is to be input, not the result of treating it as a formula).

You probably want to use the backslash to exclude elements from a set. To this end use setminus. To get the set of all integers without zero, you'd write
documentclass{article}
usepackage{amsmath}
usepackage{amssymb}
begin{document}
$mathbb{Z} setminus { 0 }$
end{document}
Also works in MathJax. Live example: http://mathb.in/29559

I was aware ofsetminus. As I said in comments, the symbol is for represent the{}) but I wanted to display it in math mode, so I think the appropiate symbol isbackslash.

@manooooh - You wrote, "I think the appropriate symbol isbackslash". That's not quite right, sincesetminushas math type "mathbin" ("binary operator"), whereasbackslashhas math type "mathord" ("ordinary"). In order to get the typographically proper amount of spacing around the backslash character, what you would need to write ismathbin{backslash}.
