It reminds me of the math "puzzles" on Twitter which go:
1 shoe + 1 shoe = 2
2 shoes + 2 shoes = 4
3 shoes + 2 shoes = ???
And the answer isn't 5 because a) we're not counting shoes and b) the shoe laces were different colors. There's nothing clever, it just teaches you to be hyper cynical and question every little detail which isn't relevant to either Math or the real world.
