very cool but i had to much time on my hands soooooo...
16 bit adder
im only using 1% of my brain to understand this
also why not use 1 4 bit adder instead of 4 1 bit adders
Another way:Do what I did and make an 8-bit adder and use 2 of those.
Edit: That didn't work, it's too big and won't fit in the bounds.
