Miracle Math: How to Develop a Calculator in Your Head (Flowmotion Book Ser.)

If you look around for books or websites about arithmetic shortcuts, most of them will be about doing math problems mentally.But what about pen & paper math? What if you're happy & comfortable working on paper, and you just need easier alternatives than you were taught in school?So far, this is the only book I've found, that focuses specifically on doing math problems, Left-to-Right, on paper. There might be others, but search engines don't make them easy to find.There are sufficient drills here, to help you understand the techniques. But if you want to make it second nature - and specifically, if you want to experience a 'flow' where your hand and brain are coordinated and each step takes place smoothly, you will want to print out some math worksheets from some websites. If it's available, print out the answer sheet, as well.This is one of two main brain exercises that I perform, daily. One of them is memorizing 20-30 playing cards. The other is doing arithmetic drills, with the techniques that Harry teaches here. Neither of these exercises are intended to help me perform 'feats'. They are intended to relax oneself, while exercising the brain, and to generate a flow state.Harry's book makes the process of calculation natural & enjoyable.

There are few books available that are as good collection of tips and tricks for performing addition, subtraction, multiplication and division rapidly either in your head or on paper. IMHO, there are no _better_ books. I suggest copying the exercises in the book onto paper before solving them, since you will probably want to pass the book along to someone else and keep doing so until the covers fall off. The book's that useful. (You can always duct tape the covers back on and keep going, too!)This is an excellent resource for people who avoided math in school and now wish they hadn't. Like free throws in basketball, practice is necessary to develop the skills. But there's no pointy-headed nerd sitting behind you to snicker if you get it wrong the first couple of times, so dig in! This book is the cure for calculator-itis. Amaze yourself by effortlessly spotting the (intentional?) inaccuracies in the price-per-oz. estimates at the grocery store as you walk along the aisles. It's amazing how much more often you actually perform and benefit from calculations when you can perform them on-the-fly and don't have to take time to dig out a calculator or cellphone app and enter equations.

I loved this book so much, I recently bought 4 more copies for a friend of mine, so that they could work with their kids as if this were a school workbook...I actually bought my first copy of Miracle Math a few years back and I was hooked from the beginning. Harry Lorayne's writing style makes it seem as if this approach to calculation was a hidden secret that once discovered would make math seem so simple. I loved studying math in school but I must say that if math were this fun and exciting, I would have have become a mathematician. I do remember one of my Algebra teachers performing amazing calculations in his head and it always amazed me...But now I know his secrets!If you want to brush up on your math skills, this is NOT the book. If you want a new, faster, easier, better way to perform calculations this IS the book. This will work for children who are struggling in mathematics, but it will teach them an entirely different system than they are not teaching in school, but I guarantee you that they will be getting straight A's!I truly believe this should be a book taight in our school system.

I owned this book years ago but lost it during a move. I bought another copy and it's worth its weight in gold. Mr. Lorayne has rethought all the basic skills of arithmetic and come up with powerful and practical new ways to calculate. The prose is crystal clear and assumes almost nothing from the reader. His new way of doing division alone is worth the price of the book. His "quotations" are a bit strained perhaps but there's so much material here - all of it practical. I can't say enough good things.Curtis Stotlar

Fast shipping great item and price.

I keep one thinking

Harry Lorrayne ... nuff said.

Why in the #$&& didn't they teach this to me in school 60 years ago. As a GED instructor I'm using these techniques to "heal" math wounded students who are convinced they couldn't learn math.

Become a human calculator with Harry's help!

this book is very helpful if you are a student or need to use number a lot in your work.

excellent

Some neat tricks for gaining number "flexibility" and counting on your fingers!
