IAN: My placing the + under A was an error.
What you write is the proper "got larger" matrix,
and as I shall show, it's as valid as the first.

IAN: A reduction (-) of B in size by 1
unit relative to A (0) is expressed as
-1. -1 is LESS than 0, 0 is 1 more (+)
then -1, so in fact A has gotten larger!
Size is 100% relative. There is no absolute
size, and that's what your case requires.
That the second matrix is valid is clearly
proven by the fact that -1 is less than
0 and 0 is 1 more than -1. If we have 2
things in the universe, A and B, and B
gets smaller, it's equally true that A
gets larger, because size is relative.
So the second matrix that defines the
zero sum of all valid data = valid data.
