What is not a subset symbol?

A ⊄ B

Symbol	Meaning	Example
A ⊄ B	Not a Subset: A is not a subset of B	{1, 6} ⊄ C
A ⊇ B	Superset: A has same elements as B, or more	{1, 2, 3} ⊇ {1, 2, 3}
A ⊃ B	Proper Superset: A has B’s elements and more	{1, 2, 3, 4} ⊃ {1, 2, 3}

Why is empty set a proper subset?

S is a subset of A iff all elements of S are elements of A. Since the empty set has no elements, this condition is trivially satisfied: the empty set is a subset of all sets. S is a proper subset of A iff S is a subset of A and S is not equal to A. The empty set is therefore a proper subset of any non-empty set.
