Could you add the except ('\') symbol for Math? Isn't it kinda needed for writing stuff like "all reals except for 0" (#RR#\#{0}#)?

was how I was taught in set theory to write this; if this is no longer acceptable, would someone please post. (I've used this notation several times with no objections).

Here's what you can do.


To get the "backslash" symbol for math formatting you can write the symbol in between quote marks.

Here's what I mean

  • without the hashtags

RR "\" {0}

  • with the hashags

#RR "\" {0}#
