I slowed down about half way through this book and was ready to give it 3 stars In some cases I had discovered a fair number of the tricks on my own or had learned them elsewhere The processes described were sometimes just brute mathematics reuiring you compute then hold numbers in your head and compute again However the second half had some cool techniues that I didn t know and while 4 or 5 digit multiplication problems are just plain difficult as the author admits 3 and 4 digit suares are 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

Two stars really isn t a fair rating Had some fun adding and subtracting and then multiplying 3 digit numbers in my head But as the problems get complex my limitations became apparent Couldn t read through the entire book When I couldn t do what the book was suggesting just gave upSo no reading this book wont suddenly make you a math geniusThere 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 practiceSo in fairness the 2 stars represents the bitterness I felt upon failing to become an overnight mathemagicianbut who knows maybe you can do it

Some years ago on a whim I picked up Moonwalking with Einstein by Joshua Foer In that book the author a hitherto unremarkable journalist details how he learned memory techniues that allowed him to recall hundreds of digits of pi to learn the names of dozens of strangers in minutes and to memorize the order of an entire deck of cards in the amount of time it takes me to tie my shoes I was completely captivated The idea that someone could so radically augment his mental prowess using ancient techniues appealed deeply to me Soon I set about teaching myself some of these methods The most famous and powerful is the so called memory palace converting information into images and then placing these images in a familiar space Using this method I was able to memorize well over one hundred digits of pi I even managed to learn the order of a few decks of cardsThis was impressive in itself and a testament to the efficacy of these techniues Even so learning the techniues was itself time consuming and without significant practice I was sluggish both in committing to memory and recalling information You cannot become a memory athlete without significant practice What was worse these systems only really worked with certain types of information The techniue for memorizing cards for example was useless when it came to remembering German vocabulary So after a few weeks I gave it upI bought this book during my brief memory trick craze but my enthusiasm had worn off before I began it Thus it languished on my shelves for many years until nowThough this book is technically co authored it seems obvious that Arthur Benjamin was the driving force behind it Michael Shermer the founder of the Skeptics Society contributed an afterword in which he argues unpersuasively that these mathematical tricks and techniues somehow aid in being skeptical though a uick calculating conspiracy theorist strikes me as perfectly plausible Benjamin meanwhile contributes the real meat of the book ways to speed up mental calculation He himself is a master of these techniues which he uses for a sort of numerical magic show there are many clips onlineBenjamin has done a wonderful job in compiling this little handbook The mathematical tools are simple easy to use and effective I had become so reliant on the calculator in my phone that it was a relief and if you can believe it a real pleasure to return to doing sums and products myself The world of numbers can be unexpectedly fascinating revealing unusual patterns connections and symmetries I must admit however that I mostly skipped the last section on large multiplication problems since the amount of practice reuired to properly execute them exceeded my interest in being a human calculatorBenjamin s feats in calculation like Foer s feats in memorization show what the simple human brain can do when aided with techniues and training achieving abilities so uncanny that it can seen like magic to the uninitiated To me this fact alone is cause for hopefulness since it reveals to us the transformative power of expertise
