   This book teaches you a few principles to do arithmetics in your head but they are contained in the first two chapters on addition/subtraction and multiplication. Most of the rest of the books are about the same principles but applying to bigger numbers (squaring three digits number, doing 4-digit by 2-digit multiplication). Doing this requires keeping track of partial results in your head and combine them in the end. I don’t see a point of training my short term memory for this because I am not paid to perform such mathematical tricks daily, not to mention my answers will not be as reliable as a $5.00 calculator. So, I learned just a few tricks to do 2-digit (maybe 3-digit) arithmetic in my head but no more.

   The only practical chapter is the one on guesstimation. Even here, Only one or two tricks are new to me.

   There is one chapter on simple math tricks you can do at a party which does not involve using a lot of short term memory.

   In a nutshell, the author might as well explain the principles in 3 pages. The readers’ interest and motivation to improve short term memory will determine how much you can do mental math.
