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

Answer:

Here's what you can do.

Explanation:

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}#
