Every Boolean algebra has two identities (one for each of the two binary functions, in this case "and" and "or"). In switching algebra, those are the only two values, 0 and 1. In some Boolean algebras the two identities are different from these, and some Boolean algebras don't even have 0 or 1 as possible values.

Quiz: What is the restriction on how many values a variable in a Boolean algebra can have?
