Welcome to the PF. This is something that you should be researching and reading about on your own. You need to learn how to learn, in addition to learning the material. Try looking in your textbook, or go to wikipedia.org and do a quick search. You will find plenty of learning materials there for this topic.

If you don't understand something about what you've read, by all means ask a question here showing what you don't get (a link or a quote, for example).


EDIT -- In fact, can you show us a block diagram of the adder circuit you are asking about? That would be a good exercise for you. :biggrin:

Alternatively, a truth table for the sum s and the carry bit co for the addition of two 1-bit numbers a and b could be illuminating... :wink:
