    Hi. Im just wondering, is there any notation i can use to refer to elements ONLY in a certain set. Usually, given sets A, B and C, i could refer to elements of only set A as [tex]A \cap \overline B \cap \overline C[/tex], but is there some notation that specifically refers to elements ONLY in a certains set?

    I can't think of anything offhand. The question, as posed, is silly. Care to put it in context?

    Set difference is the usual notation: A\B is the set of elements of A that are not in B. A\(BUC) is the set of elements of A that are not in B or C.
