    ok. UPDATE: Added a zero button and extended the subtraction binary-to-decimal converter so it now converts both 9 and negative 9

    i havent figured out how to make 0+0 work on my calculator... i say you add it just for the for the sake of having it, but people dont really seem to notice (or care)

    I'm thinking about seeing if I can add a zero button (shouldn't be too hard). Just wanted to hear people's thoughts on it. Is it worth the trouble or should i leave the calculator the way it is?

    I hav absolutley no idea what you did to get 29 from 9x9! All i know to say is wait for each of the adders being used for your problem to recieve the second number in binary.

    nah. I'm done making calculators. This is as complicated as I plan on going. Plus, I don't even know where to start with dividing. I'm sure that there's some calculator that has division though

    can you allow us to divide? I wanna break it by dividing by zero.

    i got 27. You must've hit = too early. You have to wait for each of the adders to recieve the second number inputted before hitting =
