Amazing Book!!! October 21, 2008

5 out of 5 found this review helpful
I've never been good at math, but a couple years ago, I began to love Calculus and ended up taking Calc 1, 2 & 3. However, the only thing that was slowing me down was the simple arithmetic and mental calculations that I was so bad at doing. A friend recommended this book to me after I told her that my slow mental math was the reason I kept running out of time on the MCAT Physical Sciences section. I got this book two weeks ago and I've already increased my MCAT score by two whole points. This book is amazing and can really change your life. Do yourself a favor and buy it.
Thanks Dr. Benjamin!

This is a great book with lots of helpful hints at how to do mental math. My daughter wanted the book, and she is learning the material quickly.

I am not a big fan of math but I thought I give it a try. Since I have the book, I am practicing on frequent bases and the tricks really work. Beside many hours of calculation practice the book also provides some nice stories about different lightning calculators.

It's fascinating to learn ways to easily and quickly get answers to spur-of-the-moment mathematical calculations without the need for pencil and paper. Besides a I-wonder-why-this-wasn't-taught-in-school reverse technique for mentally, quickly and easily adding, subtracting and multiplying, it's especially neat to be able to determine the day of the week for any calendar date in any century! The author shows how and makes it simple. The techniques work better for those who know well their multiplication tables and their sums. If one doesn't, getting answers is doable but takes longer.
Wow! July 8, 2008

This book is great! This book teaches you tricks that really work and really makes you wonder how people came up with them.
One thing I wanted to reccommend - Although this book is for mental math, going through it, I always kept a pencil and paper by my side - some of the concepts/tricks were a little abstract to simply read and absorb the first time around, so they needed a couple of examples (on paper) to solidify the 'trick' for me. After I worked out a couple of problems on pen and paper, I was able to grasp the ability to do them mentally.
One of the best things this book teaches is guesstimation and more importantly, how to forumulate your 'guesses' so you are not so far off from target. I had been doing guesstimation for ages but the methods mentioned in the book were pretty good guidelines for my future guesses.
This book is a must have for anyone that is afraid of numbers because these simple tricks will make difficult math problems a little easier to deal with. The time saving techniques this book is filled with can shave seconds off of your problem solving skills which, come test time (math test, SAT, any test which involves math), you'll be thinking about this book and thanking the author.
