Lo compré para pasar el rato.

This book is about the important and today much forgotten skill of doing math in your head instead of on your phone. A good way of keeping your mind sharp and nimble.

This is a fun book for adults and children who like math and convenient mathematical tricks that will allow to quickly solve a variety of math problems in your head. This book makes math fun! Recently I visited family in Chicago. My great nephew is inquisitive and is advanced in math. Our mutual love for math makes it very easy to communicate with this youngster. Although he is only 10, I was able to teach him one of the tricks in the book that most adults do not know. If you want to square a two-digit number that ends in five, the last two digits always end in 25. To discover the digits that come before 25, multiply the first digit by itself and add the first digit to it--for example 35 x 35, 3 x 3 + 3 = 12, so 35 squared = 1,225. Another example is 95 squared. 9 x 9 +9 = 90, so 95 squared = 9,025. There are 231 easy to follow pages in this engaging book with numerous tricks and problem solving techniques with answers that follow the problems or in the back of the book. Though my great nephew is hampered by a medical condition that is not conducive to good communications with some people, his math skills are far beyond his age. I know that he will be intrigued and have a blast with this book and can hardly wait for him to use it. This book will not only make you seem smarter, it will make others think you are a mathematical whiz and they will be correct. Math can be and is fun when you master books like this one. Enjoy! I recommend Secrets of Mental Math by Arthur Benjamin and Michael Shermer to friends, family, and others who would like to increase their mathematical skills in a fun and easy manner.

Un très bon livre qui regorge d'astuces pour calculer toujours plus vite et sans papier, ni crayon, ni calculatrice. Pour ceux qui seraient rebutés par l'idée d'acheter un livre en anglais, le vocabulaire employé est très simple à comprendre.

My mental arithmetic was fairly good before purchasing this book but I wasn't exceptionally quick so I looked for some help in speeding things up. While reading this book I discovered I had been using the right to left paper method rather than using a left to right method. It's brilliant and works so fast. I actually feel cheated that I wasn't taught this stuff at school as it makes it so much easier. I will definitely be using this to help my kids mental arithmetic improve too. Awesome!
