Union

Summary

The union of sets is the set of all objects that are elements of at least one of the sets.

What this node needs for W2
  • edge equivalent in: a statement for each pair of definitions that a source proves equivalent (0 of 1)
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
