Fortunately I also purchased "Math Doesn't Suck" when I purchased this book because this book doesn't even mention things like mixed numbers and improper fractions. Ignore the girly dribble in Math Doesn't Suck and you'll learn a great deal more about math than in this book.

After seeing this author reviewed on the Colbert Report, I ordered it for my 12 year old grandaughter. Her mother tells me that she has spent hours in her room reading it. This has been followed by endless statements like "Go ahead ask me the square root of ...." It is a winner!

I must say this Kindle book was a nice surprise - although the topic might discourage many people from browsing this book at all, I find the book to be very well written and appropriate for all audiences regardless of educational background. Formatting on the Kindle is overall acceptable, but with the occasional missing word or sub phrase, like in this example in Locations 2933-42 "Thus February 12, 1809, has and 14+14 = 0, so ..."

Great little book. Basic math should be taught this way in all schools. The way we teach now creates problems with math for the majority of people. The United States is 24th in math scores world wide. What is insanity, doing the same thing over and over the same way and expecting a different result? That is what our educational system does. This book gives us a fun and effective way to teach basic math so our kids continue on to the more complex and fun stuff.

I ordered this book to make up the difference to qualify for free shipping from Amazon. Turned out to be a fortuitous purchase. My 9 year old now gets a kick at being able to multiply numbers like 81x89 in hear head in less than 5 seconds. I've also learned a few things myself as well.
