We don't know how this multiplication trick works, but it's
never failed us yet. Take any two
numbers: say, 116 ahd 3,011.
Halve the first number again
and again, discarding any fractional remainder, until you reach
the number 1. Thus: 116, 58, 29,
14, 7, 3, 1. Double the second as
many times as you halved the
first. Thus: 3,011; 6,022; 12,044;
24,088; 48, 176; 96,352; 192,704.
Write these series alongside
each other, and cross out every
even number in the halves column and its partner in the doubles
column. Thus, as shown in
the following columns, the even
numbers in the halves column
(116, 58, and 14) are crossed out
along with their companions in
the doubles column (3,011;
6,022; and 24,088), regardless of
whether these are even or odd.

Add the numbers that remain in
the doubles column only. The resulting sum will be equal to the
product of the two numbers you
started with.

Thus: 12,044 + 48,176 + 96,352 + 192,704 = 349,276 = 116 X 3,011.
