    Hi name is Chris and if someone could help shed some light on this subject that would be much appreciated.

    In my homework there is a schematic of a circuit. THen is asks to algebraically determine if it is a full adder. I understand that I should write down the output of each gate but if the sum and carry out is zero, what would the equation look like? How could I verify that the equation is equivalent?

    Can you post up the schematic? How many bits are we talking about?

    When you say 'algebraically' I assume you mean comparing binary values?

    Have you tried inputting two different binary values, and then comparing the binary output?
