Robert,

Others may disagree, but I think

that expression is actually

a fairly straightforward thing

to put on the table. Doing so

though, involves expanding

the problem statement or

expression so as to also

illustrate (approximately)

the symmetry/invariance

with abstract mathematics.

(That is, to also show the

symmetry that accounts,

albeit, perhaps only intuitively,

for the unreasonable

effectiveness of mathematics.)
