Bitwise operation

How are simple operations like adding and subtraction represented using only bitwise operators such as &, |, ^, >>, ~, and <<?

Also, do each of the bitwise operators perform at the same rate, or are some faster than others?

That's not actually better than the one or two idiots hating on Xarn because they're jealous of the attention he gets (or because they think their imageboard culture can be transplanted onto world4ch).
