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.

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.

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, rappresentato da ⊂, indica che un insieme è contenuto in un altro ma non è identico ad esso. Ad esempio, se abbiamo gli insiemi A = {1, 2, 3} e B = {1, 2, 3, 4, 5}, può essere espresso come A ⊂ B, indicando che A è un sottoinsieme di B. Cos'è il simbolo "Sottoinsieme di o Uguale a"?
It turns out that the number of subsets can be found by raising 2 to the number of elements in the set, using exponential notation to represent repeated multiplication. For example, the number of subsets of the set L = { newspaper, magazine, book } is equal to 2 3 = 2 ⋅ 2 ⋅ 2 = 8.
