# UnsolvedMath Compatibility Mapping

UnsolvedMed preserves 100% compatibility with the core fields of [`ulamai/UnsolvedMath`](https://huggingface.co/datasets/ulamai/UnsolvedMath) while adding structured medical-evidence enrichment:

| UnsolvedMath Core Field | UnsolvedMed Field | Notes |
|---|---|---|
| `id` | `id` | `UMED-000001` to `UMED-010100` |
| `title` | `title` | Concise neutral title of the medical uncertainty |
| `statement` | `statement` | Specialist self-contained canonical question |
