Question

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 1

`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).

Explanation:

(It was a long time ago that I took set therory).

Answer 2

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}`
