See, my point here is that - based on the scant information in the teaser - randomly deciding to apply pure maths and trying to divide zero by 2 is not answering the question. Or at least, not answering any interpretation of the teaser that makes sense. You've provided "an answer", sure, but not one that's any help.
It's a bit like me asking someone at a bus stop how frequently the buses run, and instead of them working it out based on whatever evidence is at hand they multiply the current time by 10 and claim that's the answer. Or like atinymonkey standing just over there --> shouting "the answer is green!" because that's the colour of the bus.
Like MrL says, there is no mathematical answer because "cold" is not a mathematical function.
