This book is great if you want to learn how to do arithmetic in your head quickly.
Why would you want to do this? Because every phone interview with a hedge fund or trading firm starts out by asking you to do a bunch of arithmetic in your head quickly. Plus, it's nice to be mathematically competitive with 9 year olds in India.

Go green and save your calculator electricity

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.

Really good program to increase mental math. Not much is given to why the methods worked and I mostly enjoyed reverse engineering them. It is interesting how many I can reconstruct based on multiplying binomials appropriately set up, or general properties of distribution.

My mom bought this book for us when we were little. Unfortunately, none of us liked math much when we were 4, so it disappeared somewhere in our house. But she found it recently and it's really good.

Lots of helpful techniques in this book. Even though you'll never remember every tip and trick, you nevertheless increase your capacity to conduct mental calculations. I really enjoyed this book's fast pace and high volume of exercises, which forced me to handle and think about numbers with a level of intuition that I had never had before.

Anyone who was afraid of math should get this book; it will change your perception of math before you know it.

So glad to have this book on my shelf. I'll have to keep refreshing these tricks, but a few are easy to remember.
