Yonkey.   But 2a in math is the same as aa, it just simplifies to 2a.

W4U.  I disagree, in mathematics  2a is a multiplication, not an addition or a concatenation.

Wait a minute, this is starting to sound like a theological argument.  😉

concatenation = a series of interconnected things or events.  &.   the action of linking things together in a series.

Right. It’s more about nourishing the soul than its definition.  And it was meant to be more poetic than scientific.

Fun discussion.
