| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Basic Algebra (algebra_basic) | historical_predecessor | 75% | expert_inference | Basic Algebra is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. | No sources recorded. |
| Printing Press (printing_press) | enabling | 68% | expert_inference | Printing Press provides a capability that enables this technology without being the only possible path. |
