SETS problem

  1. Feb 15, 2007 #1
    this is another problem which i dont know how to start..im not sure which proof i should use to solve this problem
    the problem is:
    If A,B,C,and D are sets, does it follow
    (A Φ B) Φ (C Φ D) = (A Φ C) Φ (B Φ D)
    the symbol that is separting the characters is called the oplus symbol, thats the closet symbol i could find
    the oplus symbol is a circle with one line going across it and one line going down

    Darned if I know because I can't tell what symbol you used! Either write it out in letters or use LaTex.
