It’s a nerd’s dream come true for me. I checked it out from the library and had arthr for at least two months. It pained me to give it back. I’m going to buy it soon mathemqgic I get money. These tricks are so wonderful, it’s a wonder they didn’t use these in school. I loved the Pi part. I can recite Pi to a hundred digits now! Always been a goal of mine too. I was content with knowing it for 20 digits, but this made it super easy to know it to a hundred.

Then the figuring out the weekday when you have a date. The multiplying is really neat too. I’m cheesing writing this. If arfhur only read one part, I suggest the Pi bit. May 20, Phil Sykora rated it really liked it. Foreword by Bill Nye? Watching him was definitely the greatest time I had in science class. Knowing that he advocates this book or was bought out to support it is pretty much worthy of my attention. No question there is definitely useful to the point of being necessary information in this book.

In the first chapter ironically Chapter 0I was introduced to a smorgasbord of various tricks that became immediately useful: Beyond that, I learned how to do pretty much all math in my head. Squaring any two digit number above 30 was something I thought was reserved for savants like the guy from Pi.

I feel nerdy as hell for praising the book this much but it really is that good. You might not want to be bogged down with explanations of how to square three digit numbers in your head but I would recommend anyone to read Chapter 0, then see how they like it, or evaluate if it’s going to be useful to them.

Arthur Benjamin’s mental math tips are very easy to learn, yet still appear impressive to the casual observer. Towards the end of the book, there are some real showstoppers, but even if one only gets halfway through the tricks, you could still impress people at a party a very lame party.

In some cases I had discovered a fair number of the tricks on my own, or had learned them elsewhere. The processes described were mathemagc just brute mathematics, mathe,agic you compute, then hold numbers in your head and compute again.

However, the second half had some cool techniques that I didn’t know, and while 4 or 5-digit multiplication problems are just plain difficult as the author admits3 and 4 digit sq I slowed down about half way through this book and was ready to give it 3 stars. However, the second half had some cool techniques that I didn’t know, and while 4 or 5-digit multiplication matheagic are just plain difficult as the author admits3 and 4 digit squares are more doable than I would’ve thought, and perfect cube roots of numbers with up to 6 digits are so easy it’s fun.

With the neat mathematical “magic tricks” at the end to cap it off, this book was back up to 4 stars for me.

There are some interesting stories with interesting perspectives, but not enough to inspire the me to practice the “tricks” and yes I expect the average person will need to practice. So in fairness the 2 stars represents the bitterness I felt upon failing to become an overnight mathemagician View all 3 comments.
