The subset symbol is used in math to describe the relationship between two sets. Typically, the symbol is used in an expression like this: A ⊂ B. In plain language, this expression means that the set A is a subset of the set B. Read more.

In our first lecture on sets and set theory, we introduced a bunch of new symbols and terminology. This guide focuses on two of those symbols: ∈ and ⊆. These symbols represent concepts that, while related, are diferent from one another and can take some practice to get used to.

Symbol Meaning Example { } Set: a collection of elements {1, 2, 3, 4} A ∪ B: Union: in A or B (or both) C ∪ D = {1, 2, 3, 4, 5} A ∩ B: Intersection: in both A and B: C ∩ D = {3, 4} A ⊆ B: Subset: every element of A is in B. {3, 4, 5} ⊆ D: A ⊂ B: Proper Subset: every element of A is in B, but B has more elements. {3, 5} ⊂ D: A ⊄ B

The ⊂ symbol, commonly known as the "Subset Of", is a fundamental mathematical notation used in set theory to indicate that one set is a subset of another. In other words, every element of the first set is also an element of the second set. Understanding the Subset Concept.
Il simbolo Sottoinsieme di, denotato come ⊂, è usato nella teoria degli insiemi per indicare che un insieme è un sottoinsieme di un altro ma non è uguale ad esso. Il simbolo Sottoinsieme di o Uguale a, denotato come ⊆, indica che un insieme è sia un sottoinsieme di un altro sia uguale ad esso.
Set A A is a subset of set B B if every member of set A A is also a member of set B B. Symbolically, this relationship is written as A ⊆ B A ⊆ B . Sets can be related to each other in several different ways: they may not share any members in common, they may share some members in common, or they may share all members in common.
