Concept
Level
Explain this so I truly get it: {CONCEPT} My background: {LEVEL} Do it in layers: 1. The one-sentence version a 12-year-old would understand. 2. The plain-English explanation with one good analogy. 3. The 'so what' — why it matters / where it's used. 4. The part people most often get wrong. 5. Three questions to check I understood (with answers hidden until I try). No jargon unless you define it the first time.
