review Secrets of Mental Math The Mathemagician's Guide to Lightning Calculation and Amazing Math Tricks 103 Lightning uick calculations and amazing number tricks This book will teach you to do math in your head faster than you ever thought possible dramatically improve your memory for numbers and maybe for the first time make mathematics funYes even you can learn to do seemingly complex euations in your head; all you need to learn are a few tricks You’. 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 pretty much worthy of my attentionNo uestion there is definitely useful to the point 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 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 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 suare 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
