I’m told that Burger King tried to introduce a burger with one-third of a pound, to compete with McDonald’s Quarter Pounder. But many consumers thought that the former had less meat than the latter, since 3 < 4. Cris

Is there anything mathematically interesting about today's XKCD, https://xkcd.com/2313, "Wrong Times Table"?
It's commutative, or at least no exceptions can be found. But it is *not* associative. There are 48 ways to test associativity, and it passes exactly 24 and flunks exactly 24, which is slightly interesting.
None of the rows or columns is monotonic. Many rows and columns have duplicate numbers. Not all the entries are integers. There's a zero divisor.
