# The \not\mid symbol is not working well

I have seen a lot of issues regarding LaTeX being posted here and very recently i have noted one LaTeX. The \not\mid Symbol is not showing properly. It's showing like this: $p \not\mid q$. You may check this post: Importance of Cayley's theorem

• It rendered for me after I refreshed, but you shouldn't be using \not\mid: \nmid looks much nicer. Nov 12 '10 at 19:23
• @Qiaochu: It was giving me error! Let me check $p \nmid q$

• @Qiaochu: yes its giving me error! $p \nmid q$

• You can use a\not|b $\to a \not| b$ but it renders poorly as you can see. Both of these problems should be fixed since "not divides" is a common thing to say in number theory. Nov 12 '10 at 20:08
• @Bill: \nmid is available in a standard package, I think amsmath or amssymb. I don't know why MathJax doesn't support it. In any case, it's not a math.SE issue, it's either an SE issue or a MathJax issue. Nov 12 '10 at 22:07
• To get $\nmid$ to work in MathJax, one needs to configure MathJax to load the AMSsymbols extension. This is a job for the math.SE admins.

• It's a LaTeX issue; if you type \not\mid or \not| in LaTex/TeX, it renders as poorly as it is rendered by MathJax; that is, after all, why \nmid was created in the first place... Nov 13 '10 at 21:51

As Rahul stated in the comment, we need to enable AMSsymbol to support \nmid. However, what AMSsymbol does is simply assign \nmid to ∤ (U+2224), so you could use the latter as a workaround now.

p ∤ q


$$p ∤ q$$

See Tex \implies symbol does not work for detail.

This is completed as you can see here

Please enable AMSsymbols extension for MathJax

• Thanks a lot for this! Nov 21 '10 at 20:47
