 Essential for the novice bookkeeper August 23, 2009

A few years back, I had just started a job in payroll and was using a calculator to do things I really should have been able to do in my head. Quite frankly, this made me pretty terrible at that job. I had just figured I was not a "math person" with bad "number sense" and was not very long for that job without some help.
Lo and behold, a supervisor recommended this book when I expressed my concerns and willingness to do whatever it took to become better at my job. With a little work over the next month or so I proved myself entirely wrong at not being a "math person". There's no real magic to calculations in your head, but some techniques are better than others, especially for error-checking. A bit of hard work at drills and memorization can make you that much better. I stayed in the job for 3 more years and when I left I was one of the top people in a large office (200+) in terms of accuracy.
Provided you're not lazy and do the drills in the book, you'll increase your computation time after learning the practical tricks that bookkeepers have used for decades that the academy doesn't know and that your teachers never taught you in school (e.g. the division by 3 check, digit checks, adding from right to left, grouping tens, etc).
No academic jargon or nonsense or high-falutin theory. Just a regimen for improving your mental calculation speed designed for business. It's like exercise. It takes continuous work over time, and it's not always fun, but the results are worth it. Everything worth doing takes work, so beware of any "magic math systems" that instantly make you faster. There are no steroids when it comes to math.
If you're new in a payroll, bookkeeping or other field that requires fast mental calculation, an absolute must have.

If you have a need to add, subtract, etc. many numbers quickly without the aid of electronic devices: this book will help you. It also might be of interest to mathematics teachers. Otherwise, don't bother: your $4 calculator from the grocery store will do just fine.
 it sucks!!!! sorry!!! buy BILL HANDLEY'S FULL COURSE IN SPEED MATHEMATICS July 10, 2005

I personally find the review very apalling,the good fact of this book is there are lots of drills.I recommend BILL HANDLEY'S full course in speed mathematics for a very simplified straightfowrad approach.THIS book doesn't really teach you a art of calculation,but continuos drills of different calculations.Horrible book don't buy it only if you like to practice continuous drills.garbage!!!!

Being fairly proficient in "mental math", I picked up this book to see if there were any useful techniques for calculating. I was very disappointed.
The author's approach seems to rely primarily on rote memorization and optimizing pencil & paper methods. This is fine if you have pencil & paper handy, but cumbersome if you want to "run a rapid mental check..." as they suggest in their book. Rather than provide new techniques that work for mental computation, the reader is asked to perform endless drills to allow you to mentally perform pen & paper methods.
Another problem is the reliance on memorizing special cases instead of focusing on general-use techniques. If it takes a person 10 seconds to determine which of the dozens of special cases applies to a particular problem, then he does not know "how to calculate quickly"
For example, one of the author's special cases, "Multiplying a Sum by a Difference," actually has a very broad use for multiplying any two integers, but it is presented only briefly as a very narrow application that you will likely never stumble across in real life (e.g. multiplying two integers whose units add to 10 and the tens have a difference of 1)
Overall, the heavy reliance on rote vs. technique makes this an unsatisfying work.
