The method works for all numbers, and it works either way you arrange your original terms. Johnny Ball presents the method as a fun thing he was taught long ago while hanging out in the "children's room" of a pub. Never change, U. The person who taught it to him called it Russian multiplication, and Ball explains that the method originated not in Russia, but thousands of years before in ancient Egypt.

And, critically, the method maps to a binary number system. Binary is the common term for what's technically the base-2 number system, where values are represented by 0 and 1 positioned in powers of 2. Here are a few integers written out as binary values so you can see the value at each position.

If you're noticing that the "halving and doubling" method bears at least a superficial resemblance to how binary values double from column to column, you're right.

Making binary numbers from decimal base values is kind of like making change: you find the highest denomination that fits your number without going over, then subtract it. Then you find the highest denomination that fits your new number without going over, and subtract that.
