Query: MANY errors! I would NOT recommend it...

I would not recommend this book. I was tutoring someone today in mathematics and so far I've found many math problems that have typos. This book was NOT carefully edited. These are not mere typos either. Either the problem will be incomplete, the answer will not be in the options, or the explanation/solutions will solve a different problem than asked. I am shocked that such a reputable company let this book get by with all of these errors. Avoid spending your money on this one.
