A 64 BIT Calculator in Minecraft using the simplest redstone parts!

Thank you for watching! \ As a second large scale Redstone project, I decided to try and build a 64 bit Calculator, with numbers as large as 9 223 372 036 854 775 807. \ And because i wanted to challenge myself a little more, I used only Redstone wires, repeaters and torches, for the computing.
