Fascinating subjects, all. Did you have a specific question? Are you having some sort of specific difficulty? Or did you simply expect one of us to spend hours condensing an entire half-semester of beginning algebra into one of these little answer dialog boxes? Here, let me give you a clue, since you are quite obviously sadly lacking in that regard -- go read the instructions for posting questions on this site. Then read them again. And again, if necessary. Only when you are quite certain you understand your obligations as a person seeking help should you attempt to ask another question.
