1) We need to know the rules of the challenge, what is the target technology? -There is no target tech, simply creating it using 7400 integrated circuits on a bread board. 2) Is there a carry input to the first stage? -I'll get back to you on this. 3)Is the design restricted to...

Slight update there should be a not gate where it says "carry-out" Somewhat... but not entirely. I've seen them online but I have no formal experience other than reading them.

Yeah I just realized that, how about this? While that is a 2-bit adder it is designed with gates other than NAND. Granted I could simply replace each gate with the NAND equivalent, I kinda want to make this with the least amount of gates possible. Which is why I have come to this forum to see...

Greetings, I just wanted to post a 2-bit full adder I have been working on and which I think is my final design. I wanted to ask if there was any way that I could make it with less logic gates? Any advice is appreciated!
