It only does addition, and it only adds up to 15 at the moment, thinking of ways to make things more compact and complete. Connected the overflow to show "Er" if sum is > 15.

last update on this post! i removed my "fixed" adders because they were adding too much delay. i reverted the adding circuit to an old copy i had and merged my "Er" addition for overflow. it seems to work pretty well. If it adds wrong for you, sorry, but i won't be updating this save again... You will have to use a different calculator for your homework.. I am actually going to focus on the new calculator with a bigger adder to add bigger numbers, and possibly subtraction as well.

6+6 now equals 12... I duplicated my spark delayer to BOTH sides of the equation, so just about everything should be accurate now...

Just kidding again, it is much more broken than i imagined... timing spark is hard :D

Just kidding, i found the issue and adjusted the spark delays. Every noted error in the comments has been fixed as far as i can tell ;)

i see that some calculations are still incorrect. I am rebuilding this from scratch to remediate. There is a "data timing sync" issue with the adders where a bit might get lost occasionally on some calculations. Oh well!
