If you or perhaps your child,has difficulty with mathematics,the Trachtenberg system is well worth a try. Arithmetic is to mathematics as spelling is to poetry.more I'm referring to the idea that arithmetic IS mathematics, and that being good at mathematics means being good at arithmetic. This book strongly encourages a misconception that some people have about mathematics. Lastly, I have to complain about one more thing. This kind of statement may have *almost* made sense in 1960, but today. Well, the mechanical brain sitting on my desk right now can do millions of arithmetic operations per second. The foreword claims that students using this system faced off in a test of arithmetic against "mechanical brains" (did people really call computers that?) and the students won. In fact, the book strongly implies the contrary. Plus, unfortunately, the book does not make clear that it is possible for a calculation to pass this error check and still be incorrect that is, when the check says you're wrong, you're wrong, but when it says you're right, you're only *probably* right. One very good thing mentioned in this book is the error checking method "casting out nines," here called the "digit sum method." However, this is not original to the system it has been around for hundreds of years (as the book admits). The methods usually involve less writing down intermediate steps, but all the same calculations are there.

TRACHTENBERG SYSTEM OF SPEED MATHEMATICS HOW TO

For instance, instead of memorizing, say, the times table for 6, you memorize a rule for how to multiply a digit by 6. They are described in such a way that it may not be immediately apparent that that's what they are. It mostly consists of reworkings of the standard multiplication/division algorithms. Unfortunately, I don't believe this system is helpful.

So I thought maybe there were other algorithms out there that could improve my accuracy here, and I ordered some books. I have actually written the following on a Calculus test: "6 + 3 = 8." Usually I'm not quite that bad, but when adding/multiplying large numbers, chances are extremely high I will make a mistake. So, to help me prepare I bought a few books on. I'm taking the General GRE in a couple weeks and the Math Subject GRE not long after. I'll be applying to graduate school for math in a few months. It is the perfect way to gain confidence with numbers.more He devised a set of rules that allows every child to make multiplication, division, addition, subtraction and square-root calculations with unerring accuracy and at remarkable speed. Jakow Trachtenberg believed that everyone is born with phenomenal abilities to calculate.

TRACHTENBERG SYSTEM OF SPEED MATHEMATICS SERIES

Using a series of simplified keys it allows anyone to master calculations, giving greater speed, ease in handling numbers and increased accuracy. Described as the 'shorthand of mathematics', the Trachtenberg system only requires the ability to count from one to eleven.
