I do know | 3x + 4y + 12z | = 13, but I haven't learned how to do even
simple Clifford operations like 1x * 1y = 1xy in my head with clarity.
I think I got that one right but I don't see it. I need a Clifford
Arithmetic Primer! Not a text, I have access to those, I am talking
about doing simple operations on paper.

You might try starting with this:

http://en.wikipedia.org/wiki/Exterior_algebra

Note that what you are calling "Clifford numbers" is usually called the
exterior algebra or Grassmann algebra, whereas mathematicians mean
something a little more complicated by
Clifford algebra. Why the geometric algebra people seem bent on
renaming things I don't know.
