Ordered pair
Definition
An ordered pair has a first entry and a second entry , with this property: In set theory, the Kuratowski definition is . It has the property above.
Remarks
In general , but the sets and are equal. Ordered pairs are the elements of a Cartesian product. An ordered triple can be defined as .
Explanations
L1 human
A point in the plane is an ordered pair of coordinates. The points and are different, so the order matters. The Kuratowski definition only shows that sets can model pairs.
What this node needs for W2
- edge instance_of in: one example (0 of 1)
- edge not_instance_of in: one non-example that fails one clause (0 of 1)
The writing levels say how complete the text of a node is. They do not measure its truth.
