Default another beginner question - prop identification

So what, exactly, do the numbers associated with props stand for? Example, a 20X10 ... I know that the diameter is 20", so what is the 10 all about? Does it have to do with the pitch of the blades? please enlighten me. Thanks in advance for any responses.
