Help with 'connected sum" symbol #

[Math Amateur]

I just completed a post in the Topology and Advanced Geometry forum regarding the connected sum of two projective planes.

I wanted to use the symbol # for the connected sum as is usual in the topology books I am studying - but just typing in the symbol 'upsets' latex and so my post cannot be read!

Can someone please tell me how to produce the symbol # in latex?

This is true of a number of important symbols in $\LaTeX$: $\$$, $\#$, $\&$, $\%$, $\_$, $\{$, $\}$. For a rather exhaustive, and possibly exhausting, list of $\LaTeX$ symbols, go here.
