Great book!

After growing woefully bad at mental arithmetic, I purchased this book in preparation for an MBA program this fall. It is amazing how much "Mental Math" has helped me regain my confidence and improve my math skills. You should note, however, that this book doesn't offer any magic secrets. The book offers systematic approaches toward mental math, but it takes practice and effort to master these basics. I tend to practice by pulling numbers off of license plates while I'm on the road and performing different arithmetic operations on them in my head. To practice with more "real world" examples, I take numbers from business magazines and made appropriate calculations (percentage increase/ decrease in profits, etc). I hope you get as much from the book as I have!

Awesome

If you're enough of a nerd to even be looking at this book, you'll love it - I did.

Very useful . . . with some practice

This is a useful and fun book, but don't assume you can complete these tasks just by reading. It takes significant practice to compute these problems in your head. So, if you are dedicated and willing to put in the time, it is worth the price and the effort. Though I will never be good enough to beat someone with a calculator, I am often able to work out problems in my head to the amazement of my friends and family. That alone is worth it. This was first Kindle purchase, and I am now hooked.

Mental Math

My 16 year old daughter loved this book and sat with it for many happy hours. She found some math errors in it, which is why she only gives it 4 stars.

Brilliant book spoiled by the final chapter

I first saw Arthur Benjamin on TED and his performance was nothing short of amazing. I was very excited to see a book that explained his methods available on Amazon, so I bought it immediately. I was not disappointed at all to see some hackneyed algorithms repeated in the book. Despite being professionally involved with mathematics as part of my work, and collecting these sorts of math algorithms for ~5o years, there were quite a few I had not seen (or remembered). The book is written in a wonderfully entertaining way that makes it an excellent read; moreover it is easy to learn from. For me at least all of this was spoiled by a ridiculous redundant rant in the so called Chapter Infinity. Apparently M.S. cannot pass up any chance to promulgate his "religion" of skeptic. This final chapter does not belong in this book it is an entirely different subject and is not what I bought the book for. Unfortunately I bought the book in Kindle form so I do not have the option of cutting out the superfluous pages.
