Summary: Great book, but...
Review: ...on page 34, Problem 6-8, the answer given to B is what happens when 8E-8 is divided by 4.3E-5, but the problem asks the reader to multiply the two numbers, thereby obtaining the answer 3.44E-9 instead of the book's answer, 1.860.

Summary: One of the better "helper" books....
Review: This is one of the better books for getting a little help with Pre-calculus.

A little help, I say...

I needed a little refreshing on... Synthetic Division, Rational zeros/real zeros, a+bi, Descarte's rule of sign, real roots, and rational functions (hor/ver/slope asymptote)...

The only item it talked about from the above listed was Descarte's..I believe...

Each item that it talks about only gets one example.

I am not happy with this book. Schuam's book on Pre-calc looks a little better.

I personally believe that there is not a Pre-calc book out there that is worth 4 or 5 stars.

I wish that there was...because I need it!
