I'm pleased that there's a dialog about my work but there's some misrepresentation, some people

But actually that childish misrepresentation stuck with me, because it suddenly became clear to me why we don't do the blindingly obvious things.

And similarly for C and D in a decomposition of Y. So now in just purely mechanical way, we can expand the product of X times Y in terms of misrepresentation in terms of these smaller numbers A, B, C and D. So X times Y, by representation, is just the same thing as (10 (N 2) times A B) times quantity (ten to the (N 2) C D).
