Wittgenstein's "family resemblance" meme is gaining traction among the
mathematicians and math teachers on the math-teach list at the
Math Forum.

We've been yakking about the meaning of "multiplication".  Young children
are often taught it's "repeated addition", but will this lead to confusions

Thanks to the Wittgenstein camp, we have a more sophisticated way of
communicating the non-monolithic nature of the "multiplication" concept.
In short, we have "family resemblance".
