Good one! Although, I'm not sure that I would classify this as a "Math" teaser. Maybe the "Other" category instead? Still, lots of fun!
I was not sure what category to put it in either and they selected which one to put it in.
Love this kind of puzzle! Agree on category, but where to put it?
For whatever reason, this came to me almost immediately. Almost disappointing, I wanted to struggle with it more!

Gotta have some easy ones in there.
