Just add each digit to its neighbor and some other stuff. It's worth reading in my opinion. Sep 12, Pandu Reddy rated it it was ok.

It is intended to mean "half the digit, rounded down" but for speed reasons people following the Trachtenberg system are encouraged to make this halving process instantaneous.

So instead of thinking "half of seven is three and a half, so three" it's suggested that one thinks "seven, three".

This speeds up calculation considerably. In this same way the tables for subtracting digits from 10 or 9 are to be memorized. And whenever the rule calls for adding half of the neighbor, always add 5 if the current digit is odd.

This makes up for dropping 0. Rule: to multiply by Starting from the rightmost digit, double each digit and add the neighbor. By "neighbor" we mean the digit on the right.

If the answer is greater than a single digit, simply carry over the extra digit which will be a 1 or 2 to the next operation.
