| 11. | The axioms for integers typically define them as equivalence classes of ordered pairs of natural numbers.
|
| 12. | Throughout this section assume a type-level ordered pair.
|
| 13. | As before, the conjugate thus yields a norm and an inverse for any such ordered pair.
|
| 14. | :For those who have similar problems, you want to treat the information given as ordered pairs.
|
| 15. | The diagonal functor assigns to each object the ordered pair and to each morphism the pair.
|
| 16. | Set theory, meanwhile had moved on with its reduction of relation to the ordered pair of sets.
|
| 17. | The most natural construction, and historically the first, uses ordered pairs of members of " F ."
|
| 18. | If the Cartesian product is taken, the cells of the table contain ordered pairs of the form.
|
| 19. | Ordered triples which are defined as ordered pairs do not have this property with respect to ordered pairs.
|
| 20. | Ordered triples which are defined as ordered pairs do not have this property with respect to ordered pairs.
