If you master this book, you will realize that these are no tricks. You use this logic all the time but never realize you are doing it. Using this book, you verify what you are doing and maybe we can teach an old... O.K. I mean it is possible to pick u some new skills. There are examples, drills, and most important thought processes.
The only drawback to this book is that with the advent of cheap prolific calculators, there is no need for archaic fractions in our dismal-oriented world.
This may not be the be-all-end-all on the subject but I found it helpful from the grocery store to the IRS.
The tricks are only intresting from a mathematical point of view if you enjoy numbers and making tricks with them. Otherwise the tricks are NOT rapid. Just remebring the trick is complicated enough... useless book
