In the boolean ring that is the powerset of a given set, when you are using the additive operation (symmetric difference), the additive inverse (a number x such that a+x=0 for all a) is not its complement, as by applying symmetric difference (any elements contained in two sets but not both), you can see that the complement (all elements not a part of A is the complement of A) when added to a set results in simply the union (all elements a p...)
