Set Symbols. A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this: Common Symbols Used in Set Theory. Symbols save time and space when writing. Here are the most common set symbols. In the examples C = {1, 2, 3, 4} and D = {3, 4, 5}

The ∈ (member of) symbol indicates that an expression on the left-hand side of the symbol belongs to or is in the set on the right-hand side of the symbol. Typically the symbol is used in an expression like this: x ∈ R.
How to easily type mathematical set membership signs (∌ ∅ ∈) using Windows Alt codes. Or click any set membership sign to copy and paste into your document.
The primary meaning of the ∈ symbol is to indicate that a particular element is a member of a set. For instance, if the set A A contains the element x x, then it is denoted as x ∈ A x ∈ A. Example. If A = {1,2,3} A = {1, 2, 3}, then 2 ∈ A 2 ∈ A since the number 2 is a member of the set A A.

What are the different notations in sets? To learn about sets we shall use some accepted notations for the familiar sets of numbers. Some of the different notations used in sets are: Set of natural numbers = {1, 2, 3, ……} Set of whole numbers = {0, 1, 2, 3, ………} Set of integers = {………, -2, -1, 0, 1, 2, ………}
Mathematical Symbols. » Set Theory Symbols. et theory is a branch of mathematics dedicated to the study of collections of objects, its properties, and the relationship between them. The following list documents some of the most notable symbols in set theory, along each symbol’s usage and meaning.
