WebIn the first paragraph, we set up a proof that A ⊆ D ∪ E by picking an arbitrary x ∈ A. In the second, we used the fact that A ⊆ B ∪ C to conclude that x ∈ B ∪ C. Proving that one set is a subset of another introduces a new variable; using the fact that one set is a subset of the other lets us conclude new things about existing ...

WebHere the underlying set of elements is the set of prime factors of n. For example, the number 120 has the prime factorization = which gives the multiset {2, 2, 2, 3, 5}. A related example is the multiset of solutions of an algebraic equation. A quadratic equation, for example, has two solutions.
