Go and read today’s Saturday Morning Breakfast Cereal. It’s one of my favourites.
So that seems to work – I tried it out with 6 and 8 and I got 48. That’s right. When I got down to the section “see if you can figure it out before moving on”, I thought about it, but I couldn’t intuitively come up with a reason why it worked. So I did the only thing I knew: I proved it that it worked.
Once I finished my proof I was satisfied that the trick did indeed work. I scrolled down with a naïve expectation to find out why it worked… to be met with the same proof that I had come up with.
Huh. That’s all I’ve got, for now: huh.
