Verzamelingstekens

Verzamelingstekens, also known as set notation, are symbols used in mathematics to describe sets and their properties. The most common verzamelingstekens include:

- The curly braces {} to denote a set, such as {1, 2, 3} representing the set containing the elements 1, 2, and 3.

- The element symbol ∈ to indicate that an element belongs to a set, for example, 2 ∈ {1, 2, 3}.

- The subset symbol ⊆ to signify that one set is a subset of another, like {1, 2} ⊆ {1, 2, 3}.

- The union symbol ∪ to represent the union of two sets, such as {1, 2} ∪ {2, 3} = {1, 2, 3}.

- The intersection symbol ∩ to denote the intersection of two sets, for instance, {1, 2} ∩ {2, 3} = {2}.

- The complement symbol C or ⊂ to indicate the complement of a set, like C{1, 2} in {1, 2, 3} = {3}.

- The empty set symbol ∅ to represent a set with no elements, such as ∅ = {}.

These verzamelingstekens are fundamental in set theory and are used to express relationships between sets and their elements. They provide a concise and precise way to describe mathematical concepts and are widely used in various branches of mathematics.
