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
