Math Textbook Help

<p>I don't know if it's just me, but buying textbooks is soo confusing! I'm trying to order my textbooks through half.com because I heard it can save you a lot of money. The book list on tritonlink isn't very clear though with what kind of book to get. </p>

<p>For my Math 10c class, it is telling me that I need Calculus: Multivariable, 4th edition (the author is Hughes-Hallett), with no page numbers or anything. On half.com there are so many different versions of the same edition, and they aren't even that clear with what kind of books are the solution manuals and such. </p>

<p>I was just wondering if anyone could help me out. If anyone took Math10C, can you tell me what color the cover is and approximately how long it is? Also, do you recommend me buying the optional solution manual?</p>
