What is the symbol for contains?

⊆ The symbol ⊆ is used to denote containment of sets. For example, Z ⊆ Z ⊆ R.

What is ∈ in math?

The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.

How do you use ∈?

The symbol ∈ is used to mean “is an element of,” just as the symbol = is used to mean “equals.” For example, to say that the number 2 is an element of the set 1, 2, 3, we can write 2 ∈ 1, 2, 3. To express the opposite, “is not an element of,” we put a slash through the symbol and write ∉.
