Thank you for taking the time to respond to my ignorance!! Very much appreciated.
I understand what you're saying now. I think I'm the kind of guy that picks off more than they can chew. But that's how I learn. I do learn best in a classroom but at 86 the internet is my classroom now and I'm picking the brains of my classmates, along with some TA's.
I looked at the link you provided. I have a Master's Degree, but not in advanced math. Thanks.
