    Use of # symbol as a connected sum operator

    I have just completed a post in the Differential Geometry Forum and there is some problem with the Latex

    The post is
    Homology of Connected Sum of Two Projective Planes, P^2 # P^2

    and I am using the usual symbol for connected sum, namely #

    I have tried to produce the symbol # by using \# between the TEX labels but it does not seem to be working.

    Can someone please help.

    $In\ LaTeX:\ \#$

    Try dollar-sign \# dollar-sign.

    I have found that using beginning and ending dollar signs as delimiters for LaTeX works better at this site.

    On the forum, if you don't want something to get parsed, add noparse tags:

    [noparse]Try: [tex]\#[/tex][/noparse]

    Yields:

    Try: [tex]\#[/tex]

    (Note: noparse does not stop the parser from parsing the dollar signs).

    Oh, to use the dollar signs, you can write:

    Try: $ \$ \backslash \# \$ $

    Thanks JeffM and SlipEternal ... appreciate the help

    I have now corrected my post - actually I had to re-post as I could no longer edit

    The use of $ signs as delimiters worked!

    Thanks again to you both .. ...
