3 of my biggest redstone contraptions, one world, pure awesome!

This world includes 3 math/binary related contraptions: a counter, binary adder, and digital calculator. The counter is a work in progress (that I probably won't ever finish :P ). the binary adder is fully functional, but I would suggest that you learn the basics of binary before using, otherwise you might have no idea what anything means. The beast of them all, the digital calculator, is about 90% complete. It can add and subtract any (one digit) number with another (one digit) number. The inputs cannot be negative (yet) but the answers to some subtraction problems can be.

I suggest you check it out, at least just to see how much redstone is involved. Trust me your mind will be blown!
