And whilst you're at it, what's repeated addition got to do with me and my 
two brothers sharing equally the half-pizza left over from yesterday?

But to be fair, the quote comes from "the KS3 framework (p82 of 
examples):", and perhaps is intended to be one *example* of a meaning for 
multiplication. Perhaps the next line goes on to examples of 
function-of-a-function, Cartesian products, etc.

I'd certainly be concerned if the *only* interpretation of multiplication 
at *KS3* was repeated addition. Can anyone confirm or refute?
