An adder is a circuit that adds two binary numbers. An adder is either a half adder or a full adder. The difference is that the full adder also has a Carry-In bit, while the half adder does not. It’s made out of logic gates, like this: A Full Adder Carry-In A B Sum (S) Carry Out 0 0 0 0 0 0 1 0 1 0 0 0 1 1 0 0 1 1 0 1 1 0 0 1 0 1 1 0 0 1 1 0 1 0 1 1 1 1 1 1 Truth Table for the Full Adder HD14008B Datasheet
