It supposed to be a 4-bit binary adder with the result shown in decimal

But this version Doesn't fully function :3 sometimes it works sometimes not i guess it's a connection mistake but at that point i'm just too exhausted to search for that + the space of the canvas isn't helping either

After some testing it seems to work fine except for (15+7) & (15+3) ?? Even though it gets 9+11=22 right

I made a working one with three digits that barely fit, and I mean one more logic gate required and i'm out of space! Well, more like 5 or so. So, how exactly do you plan to do this?

Oh wait, it's an adder, not a combination lock. Well, that was stupid of me. I'm no good at those things.
