Impressive, this idiot has never heard of Cartesian product it seems. Nor I guess any of the many other non-arithmetic notions of product. Well, maybe it was another Commode language barrier moment.

LMAO. With that and your "product" foolishness, you have set back your /crusade/ to "prove" you are smart by at least a year or so. First, an English lesson for you. It's "carbon" not "Carbon".
