I like how you answered this question. It was neat and easy to see, however you should make sure that you tag it right with your name and the "textbook questions" or something like that. Right now I see a big link that links back to your post. Good answer to the textbook question though!-Nils
Good Job, Sam. I like how you used pictures to show your work, but it would help if you explained your work a bit more. I also think that you should have cropped the photo of your work and enlarged it. I also feel that the =52.234 beneath your first line of work is not necessary.
