Book Description

Have you ever wondered why some people are so good at arithmetic?

In school they rarely need calculators, preferring to simply glance at an addition or subtraction and write down the answer.

Later in life, they impress co-workers and employers alike with their rapid math skills. They race through math tests, impress employers at job interviews, and get the career they want.

So what's the secret? Are these "lucky folks" born
mathematicians?

Maybe. But probably not.

More likely they were taught how to calculate mentally.

You see, like most skills, what appears to be magic or "natural genius" is nothing more than technique.

And with the right lessons presented in the right order, just about anyone can learn the ancient art of "mental math" and acquire confident calculation skills.

In fact, mental calculation is easier to learn than you might believe. Because although "mental math" sounds complicated, all you really need is a few basic principles.

This simple guide from veteran math teacher Kenneth Williams will introduce you to twenty easy methods you can use to calculate in your head today.

The methods are perfect for beginners and improvers. Each lesson takes only a few minutes to complete. And with the fun quizzes along the way, you will prove to yourself how easy it is to calculate in your head - without a calculator.

What's more, you'll feel no mental strain or pain either. That's because Kenneth's methods are so natural, you'll wonder why you weren't taught this way before.

Ideal for kids and adults alike, How To Really Calculate In Your Head will introduce you to the proven methods of the mental calculator. Enjoy these simple, fun, and wonderfully practical techniques today.

And keep your calculator in its case.

Not every one can carry out mental calculations. Often in life the need arises and this ebook will make it less of a challenge for those that cannot carry out calculations without pen and paper. For that reason I recommend this ebook.

2.0 out of 5 stars Too little 7 April 2014
Format:Kindle Edition|Verified Purchase
There are good books explaining the many techniques one can familiarise oneself with which genuinely work as aids to mental calculation. This falls far short of introducing that topic or of even adequately covering a tiny part of it. It does have some useful tips, but not enough. Can't help but think such a book should have a count on the front cover of the number of tips inside. A good book would need a large index or a reference bibliography. The only use I can think of for this book is to persuade a very number shy person that there does exist at least a few arithmetic short cuts which they can learn. But how hard is it these days to add a reference or link to better works? Also there are many impressive tips any one of which the author might have added which would have alerted the reader to a possible richness of tips. The tips herein are few and not impressive. The author should have said as much.

The book was 20 lessons.
The offer to join
Math2020 came at the end indicating access to 400 lessons.
After my money was taken, I learn that there is a time limit and
More money is needed to access other lessons and help from the author.

5.0 out of 5 stars Trying to calculate like my 4th grade granddaughter 26 Aug. 2013
By Mariposa - Published on Amazon.com
Format:Kindle Edition|Verified Purchase
Last year, when my granddaughter came home from school, she was telling me how they calculated in their heads. I had to get paper & a pencil to calculate and she could come up with the answers before I did. So, I decided to get this book, and it is giving me her methods. Therefore, I love it! I may use this new skill at the grocery store - if I can find the prices on the shelves. With the scanners, sometimes, not sure if the prices on the shelf are correct.

5.0 out of 5 stars I'm a math tutor and I love this book 20 Sept. 2013
By Katie-girl - Published on Amazon.com
Format:Kindle Edition|Verified Purchase
Some of my students have not yet mastered their math facts. I bought this book to discover some tricks to teach those students, in order to get them more committed to learning their math facts. This is a really fun book, and is a bit reminiscent of the calculus teacher in the movie Stand and Deliver. I recommend this book!
