So, during the trip, we were listening to a story, and the reader mentioned 5 dozen things. Arianna asks what is five dozen, and I told her "It is five twelves." About six seconds later, she says "That's 60!" I said, "Wow, that was fast. Did you already know what five times twelve is?" And she says, "No, I just did five, ten, fifteen, twenty...sixty!" I thought about this, and I said, " Ah, so you turned it around and did twelve fives, eh?" She says, "Yeah(implying duh!), it's the same thing."

To which Aaron adds, "Yeah, Dad, it's the same thing, commutative property. Duh."

I love getting pwned by my kids.
