I spent a few afternoons mastering BCD addition, and here is the result! The calculator only does addition so far, but multiplication will likely be done soon. Work on subtraction will begin afterwards, and then division...? Anyways, please tell me what you think! Also, I am considering doing a tutorial on calculators. Would you be interested in seeing this? http://lbp.me/v/w2jts8

Queued will leave some feedback after playing, would you try my level and leave some feedback? Link in the sig Pretty cool level, found no bugs. Looking forward to adding playing with subtraction, division etc. good job

I've got it queued up and I'll take a look at it later. If you need some tips on subtraction, give me a shout; I've got an 8 digit adding/subtracting calculator up which also uses BCD. Multiplication's doable too using timers and counters, but takes about 7 seconds to multiply 2 4-digit numbers, even using 0.1s timers (wish I could find a way to go faster without breaking the system).

I devised a different way to do multiplication, unfortunately it was ridiculously thermo-intensive.

pretty neat. i'm getting a bug with 9000 + 3000 though. it's adding up to 11000. It should be 12000.
