    UPDATE:
    I just reworked parts of the calculator. Its speed (once I finish replacing some wires) will be greatly increased!

    Also, looking into adding multiplication.

    --UPDATE--

    This calculator now supports subtraction!

    Just in case anybody is confused, once all three digits are selected, and you press the I button, simply wait until the red light turns green, then select three more digits and press the I button again. You can change between subtraction and addition at any time. Do not subtract at start, this currently does not support negative umbers.

    The answer is displayed to the right of the LCD.

    Please post comments, suggestions and bugs here.

    Could you add signs, so people know what to do?

    Does it actually do addition? Or does it just display the numbers???

    @Dragonfree97
    Sure thing

    @Cr15py
    Yes

    EDIT:
    Ok there are now instructions. Please let me know if the process is still confusing.

    EDIT again:
    Just realized that I posted the unpublished save. The save on the first post is now correct...

    Any suggestions to improve.

    Also I am going to start adding subtraction soon, so the entire thing may break.

    (with the numbers fixed up of course.


    because at the moment it is a bit unclear how it works

    @jalfor

    Are the instructions confusing? If it is that hard, maybe I will post a vid on how to make it work.

    I do not know if I am the only one, but does anybody else completely obliterate their creation once they finally finish it? (with lava or other random stuff)
