But it was simple enough to help me grasp the concept. All the technical talk just goes right over my head. Through a simple example, even if it's an oversimplification, I'm able to get a hold of the general idea, which is really all I need at this point. Your example, while it may be more technically correct, doesn't allow me to visualize the concept, and I need some sort of visualization to get the idea. That's how my mind works. But thanks for jumping in. At some point I may understand all the math ....
