BOOLEAN ADDITION, In Boolean algebra, if A +B=Z, and A=1 and B= 1, then Z= 1. In other words, 1+1=1. The basic idea in boolean addition is that if any of the additive terms is satisfied(present), then the outcome is true(occurs). Addition in Boolean algebra is equivalent to th ee logical operator OR. (In this discussion uppercase OR is used to indicate logical OR. Thus, the statement A+B=Z becomes if a equals 1OR als 1, then Z equals 1
