new ways to think about math
I read this book about once a year. It turns arithmatic inside-out, showing quick tricks to do calculations in your head, or ways to transpose number problems to view them in new ways that make them easier to solve. For example, using the power of reciprocals, multiplying by 5 is equivalent to dividing by 2 and moving the decimal point to the right spot through a test of reasonableness. I apply many of the tips in this book regulaly in my job during the day, and the more times I review the book the more they've become intuitive. I highly recommend for anyone interested in math or numbers, or deals regularly with simple math problems.

Got me through GRE
The information gained in this book helped me through the GRE! I recommended this to all of my friends.
