Building on the previous article on Method of Complements, lets take a look at the difference between signed and unsigned integer types.

Topically, hexadecimal is extremely useful for programmers to understand, and makes binary in general quite a bit easier to work with and represent both in code and out.

Though not as important as understanding binary in general, looking at some simple math in binary will allow you to conceptualize some of the operations that you will be working with on a regular basis.

I personally believe that a basic, if not strong, understanding of the binary (or base 2) counting is crucial to understanding how computers work. And, thus, to being a good programmer.
