Where can I learn about these? In most books I''ve read, they assume prior knowledge of these, even in introductory books. Is there a site that sheds a little light onto the subject, enough to get me through DirectX and basic windows programming? Thanks for the help.

It's for assembly, but the first chapter of AoA focuses on the number systems of binary and hexadecimal, but no octal.

Octal simply means "base 8" as opposed to decimal's base 10. Hexadecimal means "base 16"

Learn hexadecimal, octal is just 'hex' cut in half so the same technique applies to both.

if i wrote this amount of x''s in decimal:

xxxxxxxxxxxxxxx

it would be 15,
so in octal would it be 17 ? right?
so in hexadecimal how does that work :p!?

AHA! i see now, that is where all the letters come in!
