    I have a upcoming test regarding circuits and one of the things covered was a 4x4 bit binary circuit.

    I saw the wiki: http://en.wikipedia.org/wiki/Binary_multiplier

    but I can't figure out what is wrong with it (the comment says something is)

    Can anyone tell me (or redraw the circuit if you have a couple minutes) and explain what is wrong with it?

    :confused:
