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?
