Trachtenberg Speed Math - Direct Multiplication - 2 Digit Multipliers

Also, the Trachtenberg system includes some specialised methods for multiplying small numbers between 5 and The section on addition demonstrates an effective method of checking calculations that can also be applied to multiplication.

This is achieved by noting that the final digit is completely determined by multiplying the last digit of the multiplicands. This is held as a temporary result.

This calculation is performed, and we have a temporary result that is correct in the final two digits. People can learn this algorithm and thus multiply four digit numbers in their head — writing down only the final result.

They would write it out starting with the rightmost digit and finishing with the leftmost. Trachtenberg defined this algorithm with a kind of pairwise multiplication where two digits are multiplied by one digit, essentially only keeping the middle digit of the result.

By performing the above algorithm with this pairwise multiplication, even fewer temporary results need to be held.

Trachtenberg called this the 2 Finger Method. The calculations for finding the fourth digit from the example above are illustrated at right.

The arrow from the nine will always point to the digit of the multiplicand directly above the digit of the answer you wish to find, with the other arrows each pointing one digit to the right.

The vertical arrow points to the product where we will get the Units digit, and the sloping arrow points to the product where we will get the Tens digits of the Product Pair.

If an arrow points to a space with no digit there is no calculation for that arrow. As you solve for each digit you will move each of the arrows over the multiplicand one digit to the left until all of the arrows point to prefixed zeros.

Division in the Trachtenberg System is done much the same as in multiplication but with subtraction instead of addition. Splitting the dividend into smaller Partial Dividends, then dividing this Partial Dividend by only the left-most digit of the divisor will provide the answer one digit at a time.

The Product Pairs are found between the digits of the answer so far and the divisor. If a subtraction results in a negative number you have to back up one digit and reduce that digit of the answer by one.

With enough practice this method can be done in your head. A method of adding columns of numbers and accurately checking the result without repeating the first operation.

An intermediate sum, in the form of two rows of digits, is produced. The answer is obtained by taking the sum of the intermediate results with an L-shaped algorithm.

As a final step, the checking method that is advocated both removes the risk of repeating any original errors and identifies the precise column in which an error occurs all at once.

It is based on check or digit sums, such as the nines-remainder method. She has also won the young artist awards three times for her work in different movies and as well as many more of the considerations.

Professor Trachtenberg fled to Germany when the czarist regime was overthrown in his homeland, Russia, and lived there peacefully until his mid-thirties when his anti-Hitler attitudes forced him to flee again.

He was a fugitive and when captured spent a total of seven years in various concentration camps. It was during these years that Professor Trachtenberg devised the system of speed mathematics.

Most of his work was done without pen or paper. Therefore most of the techniques can be performed mentally. Cutler, Ann ed. Translated by A. Cutler, R.
