If you're willing to put in the time to learn these tricks and to practice, you really can build your ability to do math in your head, and this will help you a lot in life. It's a lot like weight lifting. One essential trick: learn the inverses of all the small integers: 1/2 = 0.5, 1/3 = 0.333..., 1/4 = 0.25, etc.

This book is definitely pretty good for learning the tricks and for practicing.
