Errors
I have been using this as a tool to tutor, and have found several inconsistencies. Example: page 68 in the post test - #4&5 are incorrect in the answer book according to directions given in the lessons for that chapter. In number 4, it says the answer is 1/5, but it’s actually 5. K=y/x . Need to check your stuff people!

Riddled with Errors
First lesson: Understanding Absolute Value. "The absolute value of a number is a number that is the same distance from zero on a number line as the given number, but on the opposite side of zero. -8 and 8 are absolute value because they are the same distance from zero on opposite sides of the number line." Um, no. After puzzling over this grossly horrific lie, I realized that it was a typo. The page of exercises that followed asks the student to find the "opposite" of given numbers. And the next lesson is about absolute values, and defines it correctly. So, it's a typo. Every spot that says "absolute value" is supposed to say "opposite". A typo. But a massively huge one. Not just once, not twice, but three times (lesson title and twice in the paragraph). In the very first lesson of the book. If you don't believe me, look at the sample pages on this very web page. It's in there.
