What do double brackets mean in set notation?

2. For any expression A, “{A}” means “the set whose only element is A”. In particular, when A={x}, {{x}} means the set whose only element is {x}. That is, the double brackets have no special meaning; they are just two pairs of single brackets which happen to be nested.

The brackets stand for a function that maps a linguistic expression to its “denotation” or semantic value.

What are braces in math?
