NoVIce, correct! If I were to bump it up to 5 bits it could do 16 positive and 16 negative, but I think 4 bits is enough for now, and 8 bits would be the next step.

The first sentence doesnt make any sense but nvm im too lazy to think properly

@dominiPOL actually negative numbers are nothing more than this. This can calc with nums from 1 to 16, where the whole range is positive, ie unsigned calc. But to make it signed (to have negative numbers too), you just need to put an imaginary zero point and call everything below it negative. So to have negatives it should be from -7 to +8. or -8 to +7 (the 0 is a number too), because the range is still 16.

Um, why are the borders made of meltable material? You know there is an option to make an indestructable wall in the options?

Almist04, my original save was just the computational part, with no encoder or decoder. IT explains the details of function. The transistor block that actual calculates everything, is actually very small. In a computer, the rest of it could be integrated to save loads of space, or use better FILT methods... ID:2201481

Pretty dang impressive, but maybe you could make a smaller one for practical computer use? +1

That's one serious looking adder. Love it.
