The Ultimate Math Refresher for the GRE, GMAT, and SAT
$20.00
I am using this book to as my starting point for the GRE Quant Section. I basically went through every exercise in this book no matter how easy to make sure I knew my basics. This book doesn't have actual GRE type questions but that is okay. This is a Math review book not a practice GRE test. Wherever I did not solve a problem quickly, I knew this would be an area for me to work on. From this, I made a list of my weaknesses so went I went on to work on actual GRE math problems I knew what to look out for. I love the way the book states things simply so I can get a quick review of all the facts I used to know but forgotten.

This machine doesn't have nearly the amount of functions I was expecting! How can I calculate vectors when there aren't even trig functions!

This is the reason American children can't compete on a global marketplace. This "tool" of education is more of a tool for procrastination for the American public. L'Hopital would turn in his grave! Newton would have an aneurysm!

Such simplistic mathematics is best left to those whom the toy's description excludes - three year olds and below.

For just a slight amount more, you could get an old yet durable graphing utility which would increase the amount you could teach your child by a factor of 10!

In conclusion, there isn't enough here to warrant a buy. If I can't calculate a vector with it, it's rubbish.
