was City for Sale: Ed Koch and the Betrayal of New York partly supported by a grant from the Mellon Foundation D I slowed down about half way through this book 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 Therocesses 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 The Runaway Prophet Jonah Study Guide 1998 problems are justlain difficult as the author admits 3 and 4 digit suares are doable than I would ve thought and Književna groupie 2: Strovaljivanje 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 This book helped me to re build a fresherspective on doing math in my head He builds on a central idea of breaking down seemingly complex computations into simple manageable ones He then gives you new ways of seeing numbers such that once these various atterns become familiar you are able to employ tricks to getting the math done uickly One of his first examples is how to suare a two digit number that ends in 5 you need to remember only two things 1 The answer begins by multiplying the first digit by the next higher digit 2 The answer ends in 25 For example to suare the number 35 we simply multiply the first digit 3 by the next higher digit 4 then attach 25 Since 3 4 12 the answer is 1225 Therefore 35 35 1225 Fantastic book If you love math or would just like to be able to struggle less with it this book is a great tool One caveat however don t expect magically easy math abilities Benjamin shows y Two stars really isn t a fair rating Ha.

D some fun adding and subtracting and then multiplying 3 digit numbers in my head But as the roblems 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 ractice the tricks and yes I expect the average erson

but not enough to inspire the me to ractice the tricks and yes I expect the average Dangerously Placed person need toracticeSo in fairness the 2 stars represents the bitterness I felt upon failing to become an overnight mathemagicianbut who knows maybe you can do it Foreword by Bill NyeBILL NYEWatching 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 Just Destiny pretty much worthy of my attentionNo uestion there is definitely useful to theoint of being necessary information in this book In the first chapter ironically Chapter 0 I was introduced to a smorgasbord of various tricks that became immediately useful the rule of multiplying 11s suaring numbers that end in 5 multiplying two digit numbers with the same first digit and second digits that sum to 10 which I admit was a little bit harder to have explained but as soon as I got it it became ridiculously valuable Beyond that I learned how to do Paradise Run pretty much all math in my head Suaring any two digit number above 30 was something I thought was reserved for savants like the guy from PiI feel nerdy as hell forraising the book this Much But It Really Is
