Jann,
You have been so very helpful, I hope you do not mind another question.
I purchased, from Amazon, what I thought was a new student edition of the Lial's Introductory Algebra 9th edition.
ISBN-13: 978-0321557131
What I received is the Annointed Teachers Edition.
There are ISBN numbers inside the book I received however they are a bit confusing.
I am a bit hesitant to order another book until I have more information.
Do you have any suggestions that might help me make sure I am purchasing a new student edition?
Thank you so much for your time.
