Caution: This is the first calculator I ever made and it took me 1 week to make, so don't judge harshly. This calculator can add numbers together and the highest number it could show is 15. Enjoy Running Crysis at ultra settings in 8K 240Hz on this. :)

So your idea worked in crossing inst with inst which made me make smaller and faster full adders. And next calculator would be 6-bit and obviously faster!

vasad didn't crossing inst with inst would interfere with each other? I'll test

And you dont need to cross inst with metl, just cross inst with inst.

Good work for first time, but adding 7 and small number is problem, because the signal takes too long to overflow from first full adder to last full adder. Try sending more signals to adder and put delay before last storage. I hope this helped. Sorry for bad english i am not native english speaker.

It have some errors. 7+1=6, 7+2=5. You should spark adding unit input for a while before printing resoults, it miss bits of transfer.
