Please do your own homework. If you have been skipping class and failing to read your text, then you should be toast for the exam. A little review at this point will not help, particularly since it does not appear to be a review, but an initial introduction. You've never even heard the word "subscript?" I am not encouraged.

My views. I welcome others'.
