MATH.16:3 - Forces
| Force | Tension |
|---|
| Familiar representation and needed operations | A convenient notation can make calculation easy while omitting a required construction or recovery. |
| Recoverable data and additional choice | Recovering the inputs leaves open whether they determine the complete result. |
| General specification and existence | A universal property can identify the desired object even when it has no realization in the chosen setting. |
| Structural sameness and computational effort | Two constructions can support the same maps while requiring different work to calculate with them. |
