The half adder is called half because it is in-complete. It cannot accept a carry-in Ci from a previous stage of the addition. The truth table related to the full adder is shown below. The addition of A and B is shown by the first four lines when the carry-in is zero. The values of A, B, S and Co are identical with the values contained in the half adder table. The last four lines of the table show the addition when carry-in is 1.
