PaulS:
Maybe you're trying to teach me 5th grade algebra when I need to learn 1st grade addition. What's simple to you is not simple to me. and I'm sure if roles were reversed I'd bend over backwards to help you.
I think that where we are having difficulty is that we have no idea that you need help with 1st grade addition. So, we assume that its 5th grade algebra that you need help with, since that is what you are asking questions about.
If we answer the question(s) in ways that you don't understand, you bear some responsibility to let us know that. Berating people who are trying to help you isn't the best response.
If we know that your difficulty isn't with 5th grade algebra, but is more basic than that, we can back up and start with more basic answers.
If, on the other hand, we assume that, though the question was about 5th grade algebra, you don't even understand 1st grade addition, you'd be even more insulted, and rightly so.
can you please help me now?
