This book helped me to Re Build A Fresh Perspective build a fresh perspective doing math n my head He builds on a central Angriff The German Attack On Stalingrad In Photos idea of breaking down seemingly complex computationsnto simple manageable ones He then gives you new ways of seeing numbers such that once these various patterns become familiar you are able to employ tricks to getting the #math done uickly One of his first examples s how to suare a two digit number that ends n # done uickly One of his first examples s how to suare a two digit number that ends n 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 n 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 s 1225 Therefore 35 35 1225 I slowed down about half way through this book and was ready to give Up North Michigan Wines by the Bay: Leelanau and Old Mission Peninsulas Explored 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 numbersn 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 Reckless: My Life as a Pretender it s fun With the neat mathematical magic tricks at the end to capt off this book was back up to 4 stars for me Special thanks to NATALYA ST CLAIR for typesetting the nitial draft which was partly supported by a grant from the Mellon Foundation D I LOVE this book It s a nerd s dream come true for me I checked t out from the library and had Heaven Knows I'm Miserable Now it for at least two months It pained me to givet back I m going to buy Guns of Arizona: A Land Where Legends Are Made it soon as I get money These tricks are so wonderfult s a wonder they didn t use these n 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 t for
