C.29.2:3 - Forces
| Force | Choice the practitioner must make |
| Answer specification and obtaining a result | Preserve what counts as an answer while finding operations that can actually produce one. |
| Sufficient state and affordable representation | Retain distinctions needed by later steps without storing the whole history by default. |
| Familiar algorithm and problem-specific structure | Reuse an understood construction when applicable; exploit special structure when its gain warrants another argument. |
| Exactness and useful approximation | Match error to the receiving question instead of treating every real number as exactly available or every approximation as adequate. |
| Transparent procedure and resource efficiency | A simple construction can be a good first answer or reference calculation even when a different implementation is needed at scale. |
| Abstract operations and executing capabilities | Let available system operations inform formulation while keeping their physical correspondence separately established. |
