Binary adder

So I finished the Binary adder tutorial and here it is!

This sort of adder is the one usually used in the big calculating computers. To understand it you will need a basic knowledge in binary addition, which I will upload a video of later tonight or possibly tomorrow. And you will also need some basic knowlegde about how redstone works.

A Full Adder which is represented in the video consists of 2 XNOR gates and a few other stuff that gives the C-out signal, the Carry output.

In a chain of adders the first one looks a little different. Since it doesn't have any C-in, input, it doesn't have to be as big as the rest of them. You can see that when I show you the 2 bit adder in the video.
