Questions about parentheses, brackets

[Dirk.nl]

Hi All,

I have questions (not directly for the HP Prime, but for my understanding) about the use of the words "parentheses" and "brackets".
Has these words the same meaning? When do you use the word "parentheses" and when "brackets" ?
Has these words the same general meaning for (), [], < > and {} ?
I know, I think, rounded brackets are (), square brackets are [], angle brackets are < > and braces are {}. Is this correct? Can I, for instance above, replace the word brackets with parentheses?
Thanks in advance!
