<p>According to the penn book store, I have to buy the 2012 edition, but can't find that on amazon, do I have to get the 2012 edition, is it ok if I get an older edition? Also the book doesn't seem to be available on amazon, if anyone could proved a link of the textbook on amazon that would be great too lol. Lastly, will the same textbook be used when I take Math 104, meaning I won't have to buy a textbook for that class?</p>
<p>The textbook I used for 103 is used up through 114, not sure if yours is too. As for the editions it’ll probably change the homework numbers a bit which is a problem if you have to do homework from there.</p>
