Query: Helpful, but confounded with egregious math typos

I'm currently halfway through this book and have already found three signficant math typos in the questions. These aren't simple grammatical errors - they are mistakes in the formulas that yield a different answer than the back of the book! The answer explanations make sense if you can infer what the problem should be, but these problems will leave the reader confused more than anything else.And this is the FIFTH edition!
