Trachtenberg Speed Math Book

Introducing a brand new ebook on the Trachtenberg speed Math System.

The book covers all three multiplication methods; the Basic Multiplication, Direct Multiplication and the Two-Finger Multiplication. Addition, Long Division, Squaring Numbers, Square Roots and Checking results are also covered.

What is new in this book is I explain not only How the method works but also Why it works. We look at the math behind the method. Except for some algebraic proofs on parts of the method, this is something the original books completely overlooked.

I did not want to just know how to use the methods I also wanted to know why they worked, what was Jakow's reasoning behind the method. So I spent some time looking at what the system did and tried to see if I could find why he did it that way.

Finally, I believe I worked out most of the system. It is difficult to be sure when you cannot ask the man himself.

I found it made it easier to understand the method knowing why it was being done that way.

This is the first book I know of that is not from the original translators and authors of the 1960s book and contains additional information not found in the earlier books.

Each section on the method tells you how to use the method then there is a section on why the method works.
