I am going to do something a little different for my website in this post. I'm not going to explain any new math concepts or present any new lessons in mathematics. Instead, I'd like to mention a great little book that teaches you lots of quick math tricks so that you can learn to do complicated math problems in your head. To improve mental math abilities, you just need to learn some of these techniques that are not that difficult at all. These mental math secrets and shortcuts should be a part of a standard mathematics education!
The book that I am talking about is actually an e-book called "Fun With Figures," written by Kenneth Williams, and you can get it from his site. This "secrets of mental math pdf" demonstrates some simple tricks that you can quickly learn and be able to apply to your problems at school. It is not a long and complicated book like so many textbooks, which means that it is very easy to sit and read through it quickly. It doesn't aim to teach you new concepts (that's my job!), but rather only presents you with lots of examples and situations where you can apply the quick math tricks that it teaches.

Here is an example of what I mean, and why these tricks work: On the subject of addition or subtraction, it has always been taught to write your numbers one on top of the other, and then starting at the right side, perform the operation and proceed to the left. However, if you think about it, this is completely backwards to how our brains work. We say "four hundred and seven," not "seven and four hundred." And so, trying to do in our heads what we learn in school confuses us. It is difficult to work backwards! What some of these tricks do, for example, is demonstrate how to add or subtract going from left to right. Basically, you do the math as you say the number! And that is why it's so much easier to perform these calculations in your head. They're not backwards at all, but exactly as they should be. It is a wonder that some of these mental math secrets aren't taught in schools, because they are so much simpler than the methods that are taught instead.
"Fun With Figures" by Kenneth Williams is a short ebook that is packed full of great mental math tricks. You won't only do your math homework faster. Your friends will think that you are a genius! This book teaches you some secrets of mental math in several different sections, and each section has a bunch of mental math practice questions at the end so that you can immediately see that these techniques work. Interesting tidbits of information are scattered throughout the book, so that you can also learn some fascinating historical information about mathematics as you are studying the techniques.
