Query: publisher not responsive to error information

Like the other reviewers for this book, I found many errors. Fortunately for me, I am reviewing the material rather than learning for the first time.I can't imagine how frustrated and inadequate new learners must feel as they try to identify and apply the rules of math with incorrect answers to both examples and self-test problems. I would recommend new learners look to another book to learn Precalculus.While I have found other Wiley Self Teaching Guides to be accurate and very helpful, Wiley Publishing didn't respond to my suggestion to add a correction paper to every copy of this edition (the minimum ethical response).I would also that any one considering a Wiley Publishing purchase to check with online reviews before purchasing.
