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}

This textbook, “Discrete Mathematics: An Open Introduction”, by Oscar Levin, provides a good overview of topics in Discrete Mathematics.
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.
Just as the letters \(x\text{,}\) \(y\) and \(z\) are frequently used in algebra to represent numeric variables, \(p\text{,}\) \(q\) and \(r\) seem to be the most commonly used symbols for logical variables.

Logical notation uses symbols of two kinds: propositional connectives, such as. ^ (\and"); _ (\or"); : (\not"); and quanti ers. 8 (\for all"); 9 (\there exists"): The symbol ^, called conjunction, and the symbol _, called disjunction, are binary connectives, because each of them is used to form a compound proposition from two propositions.
Discrete mathematics is the study of mathematical structures that are countable or otherwise distinct and separable. Examples of structures that are discrete are combinations, graphs, and logical statements. Discrete structures can be finite or infinite.
