👉 "Junk math" refers to mathematical concepts, proofs, or techniques that are technically correct but lack practical utility or relevance. These often involve abstract or contrived scenarios, unnecessary complexity, or methods that do not provide meaningful insights or applications. While mathematically sound, junk math can obscure understanding and distract from more significant mathematical ideas by focusing on trivialities rather than essential principles. It's often used in teaching to demonstrate the importance of clarity and relevance in mathematical reasoning, but it can also be seen as a distraction from the core value of mathematics: solving real-world problems and understanding fundamental truths.
