Subset definition: Generally speaking, for two sets A and B, if any element in set A is also an element in set B, we say that the two sets are subsets.
If two sets have an inclusion relationship, set A is called a subset of set B.
Noted as: A⊆B (or B⊇A)
Read as: "A is contained in B" ("B contains A")
- A ∪ B = B ∪ A.
- A ∪ (B ∪ C) = (A ∪ B) ∪ C.
- A ⊆ (A ∪ B).
- A ∪ A = A.
- A ∪ ∅ = A.
- A ⊆ B if and only if A ∪ B = B.
