I do not have nature math talents like some people do but even I realized immediately that there is something wrong with this sign I saw at a gas station last night.
Mr. Monkeygirl gave me that "uh oh, now what?" look when he came out of the station and I was standing in front of my car pointing my phone at the propane display. But a quick explanation let him know that I'm not crazy (well, not completely crazy)! I hope this is just a "sticker" mistake and not a sign of the state of our education system.
So have you seen any signs that make you scratch your head in wonder?
