Title: JUNK Full of Typos
Product review: Just spent 30 min struggling with a math problem. Determined to figure out why my answer did not match PR's Turns out it's a typo! The answer is 42 and there is no choice that reads 42. The answer key reads "Select D, the answer is 42" When you look at D it reads 45. THis is the 4th time I've been screwed by a typo in this book.WHAT BUNK!Save your money.
