    No joke, unless you count my State supplied education in math. I did
mean dot operator, which is what stopped me from understanding most of the
vector stuff I wanted to know. What this shows is how much I used them
afterwards, that I didn't remember the term.

    Most of the people here cannot imagine how ignorant of math us non-math
types can be. Someone just posted an explanation of those terms that I was
completely unable to follow. It makes assumptions of knowledge that I just
don't have. I am sure it is clear to someone, but not me. I may never
understand vector math if I have to start at that level.

    I'll stick to arithmetic (at most) advice from now on.
