Subset online calculator

Subset Definition: Generally speaking, for two sets A and B, if any element in set A is an

element in set B, we say these two.

A set A is called subset of set B.

Record as： A⊆B（or B⊇A）

Pronounce as："A is included 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.

Usage example

Set a (true subset) = 4,2

Set B = 2
