At an IIT lab I made a discreet transistor half adder out of 11 NPN bipolars.

A half adder is just two binary bits input with a sum bit output and a carry bit output.

A full adder has a carry input bit ( see the table ) ( also see the logic representation ) In silicon diffusion diagram of a half adder is the last graphic.

NOW imagine a clocked binary 256 bit digital adder engine which resides in the core of a modern laptop CPU which is only a small fraction of the multy-functional processor core and you begin to amaze at the technology.

Your first question is a difficult one. The short answer is; Evenly! Beyond that is gets vary complicated. You'll need several years of electrical engineering courses to begin to understand that.

As for your second question... A simple google search will give you the answer to that.
