standard algorithm.
True enough... unless you're just a little odd, like me, and sometimes
do it in your head for the sheer entertainment value... and to (somewhat
defensively) prove to yourself that your mental powers havent slipped
too far yet. :-)

Truth be told, I use something like the cluster method in order to do
complicated multiplication problems in my head. Still, that's no
reason not to teach the standard algorithm.
