What do [] mean in math?
if using this in sets, () stands for open interval and [] means closed interval and {} is used to denote specific elements. Closed interval means the extreme numbers of the set are included in it and open means they arent. For example, (9,10] is the set of all numbers between 9 and 10 excluding 9 and including 10.
