Hallo.
I know it's completely useless and very confusing, but what are the rules surrounding parentheses within parentheses? My understanding is that, to separate a phrase, you would use "( )" first and "[ ]" to separate something within the "( )".

For example, if I want to put something in parentheses (to add a little info about it [and likely confuse people]), I would first use parentheses and then use square brackets inside.

What happens if you want to put another set of brackets within that second set?

For example, if I want to put something in multiple parentheses (to add a little info about it [and likely confuse {or annoy} people]), would I use the curly brackets as the third step?

If I wanted a fourth set, would it be "< >"?

I know there's probably no practical reason for using this many sets inside each other, and that you could easily format with different punctuation for clarity, but I want to know what is technically correct.

Thanks in advance,
Shayne
