The mathematical paradox strikes again! When you square both 2 and -2, you indeed get 4. But when you try to reverse the operation by taking the square root of 4, suddenly mathematics forces you to make a choice. The square root of 4 is technically ±2, but in most contexts, we default to the positive value. This is why Mr. Burns gets a confident "Yes" for the first question but Principal Skinner delivers that devastating "No" to the follow-up. It's that beautiful moment when someone thinks they've caught mathematics in a contradiction, only to discover that the square root function is actually multi-valued. Every math teacher has seen that exact face when students realize √4 doesn't automatically equal both +2 and -2 simultaneously. The function is playing favorites with positive numbers, and honestly, who can blame it?
