should i repeat it 100 tims ? It is a solution, HOWEVER, there should be a better way
I can't come up with any good ideas..Is this homework assignment?
Well, I would think that you have studied the very simple logic of an adder. If not STOP wasting your time here and hit the books. I well help you to see how a 1 bit adder (ONE output - high or low) can be chained to get what you want. But please do yourself a favor and go back to simple binary addition to see what adders actually do. Here is the adder example:
As you can see it was just as you thought it was. I will let you think about what a 1 bit subtractor is. Hint: Got to be similar RIGHT???
Good Luck
