HTML Question

HTML <m>: what is it?

I recently tried to post a note on facebook where I wrote

P(Tn<M)
. It got terribly deformed. I eventually figured out
<m>
had to be some HTML command, so I fixed the issue by
P(Tn < M)
. I googled for HTML
<m>
and HTML
<m>
command
but didn't seem to find anything useful. So I come here and ask: what does
<m>
do in HTML? Is it an HTML command in the first place? Note: I know mostly nothing about HTML, but I do know that if I type
<m>
in here without the code markup it simply vanishes, and if I type it in a facebook note everything after it is lowercased and every word is made to be followed by
""=
or something like that, and at the end of the note an
</m>
appears. I do know that HTML often uses
<foo> </foo>
for things, so I think this is in fact HTML. Of course I don't know if facebook or SX use HTML, so that is a guess. Could you enlighten me?

Please see Patrick Hofman's answer as the link I have provided is no longer working. As others have suggested this is not a part of standard HTML 5 but may belong to some framework from ASP.NET or javascript.

It's an HTML 5 element.
