(I know how to use the algorithm... my question is about how it can do the conversion)

What are you trying to show? 50 in binary? Russian multiplication (http://en.wikipedia.org/w/index.php?...ldid=383433098 ) ?

Looks like Egyptian multiplication.

No, I think he simply means conversion of 50 into binary. 50 = 110010 = 32+16+2.

Yes, if you look at the link I posted this is the same thing as what I call Russian multiplication.

And this method, in turn, is closely related to the binary representation of the number.
