• A variable whose value can be either 1 or 0 is called a Boolean variable. • We can express Boolean functions with either an expression or a truth table. Since the logic levels are generally associated with the symbols 1 and 0, whatever letters are used as variables that can take the values of 1 or 0. Ordinary algebra deals with the real numbers.
