I explain how an adder works in this video but i forgot the subtractor and all that differs from the adder and the subtractor is that you invert the carry line into the first adder and invert the B signal going into all adders, now it is a subtractor . (video is being uploaded should be up by midday here is my channel link for the video[will be titled Adder Explanation] http://www.youtube.com/user/RagedEclipse?feature=guide ).
