Can someone walk through this and let me know if everything is all right? I have a bad habit of making mistakes with my math and getting excited over nothing .

Please post back whatever you find. I'd like to know if you feel it's valid, if it's invalid, why it's invalid, and I'd be glad to explain how I got any particular part.
...yeah I know, reusing variables is a nasty habit but you get the idea =-P.
