Rebuild a confusing explanation with proper learning scaffolding

The following explanation of {{CONCEPT}} is not landing for me. Here it is:

{{CONFUSING_EXPLANATION}}

My background: {{MY_BACKGROUND}} (describe relevant knowledge you do and don't have).

1. Diagnose why this explanation is likely failing for someone with my background. Be specific — identify the exact moment or sentence where it assumes knowledge I don't have, skips a logical step, or uses jargon without grounding it.

2. List the prerequisite concepts I need to understand before the explanation can work. For each prerequisite:
   - Define it in plain language in 1-2 sentences.
   - Explain how it connects to {{CONCEPT}}.

3. Rewrite the explanation from scratch, building from the prerequisites. The rewrite should:
   - Define every term before using it.
   - Introduce one idea at a time.
   - Use a concrete example drawn from {{MY_BACKGROUND}} or an everyday context I'm likely familiar with.

4. End with a one-paragraph summary that I could use to explain {{CONCEPT}} to a colleague from memory.

If the original explanation is actually correct and clear, and the issue is a specific prerequisite I'm missing rather than a flaw in the explanation, tell me that directly rather than rewriting unnecessarily.
