A variable is a quantity which can change by taking on the value of any constant in the
numbering system. At one specific time, a variable can have the value of one constant a
later time, it can take on the value of some other constant. Since there are only two
possible constants in Boolean algebra, a variable can take on either of only two possible
states, 0 or 1.
In Boolean algebra, the two possible values for any variable are
