Penney: MV Calculus w/matrices VS MV Calculus

[calculusnerd]

Hello, I just started watching the online MIT videos on multivariable calculus: http://ocw.mit.edu/courses/mathematics/18-02-multivariable-calculus-fall-2007/video-lectures/ The recommended book is Edwards and Penney's multivarialbe calculus (6th edition). While browsing for this book on amazon I noticed there are two "6th edition" editions of the book:
1. https://www.amazon.com/gp/product/0130648183/?tag=pfamazon01-20
2. https://www.amazon.com/gp/product/0130339679/?tag=pfamazon01-20

Are these the same or is there a significant difference? It seems that the one "with matrices" has more pages, so I'm assuming it's identical to the other one except that it has some extra chapter on matrices or something like that. But again, the prices are very different (the one "with matrices" is much cheaper) so I assume there is some bigger difference between them. (Note: The one recommended by MIT is the more expensive version of the 6th edition, but I'm hoping they don't only recommend it over the matrices one simply because it is more expensive!)

Thanks

The price differences are likely due to supply and demand. There is less demand for the cheaper one. Be prepared to do work figuring out which page and problem numbers are intended if you do not get the exact book that is recommended.

https://www.amazon.com/dp/0130084069/?tag=pfamazon01-20heres one with both parts, single and multivariable, for $6. there is essentially no huge diffrence in any of their books, except the problems got easier as the edition num,bers got higher and they took out more and more deep content such as Keplers laws and proofs of theorems.
