Basic concepts in set theory

Singleton (mathematics)

In mathematics, a singleton, also known as a unit set or one-point set, is a set with exactly one element. For example, the set is a singleton whose single element is . (Wikipedia).

What is a Subset?

Math subsets are an important concept to understand. So what is the subset definition in math? What is a subset? We go over that part of set theory in this video as well as some details on the empty set and its subset properties. Enjoy! I hope you find this video helpful, and be sure to a

Number theory Full Course [A to Z]

Number theory (or arithmetic or higher arithmetic in older usage) is a branch of pure #mathematics devoted primarily to the study of the integers and integer-valued functions. Number theorists study prime numbers as well as the properties of objects made out of integers (for example, ratio

Vexels and Polynumbers via Multisets | Algebraic Calculus One | Wild Egg

In this video we introduce a data structure definition of polynomial, which we call a polynumber. This builds on the idea of a vexel, which is a more general data structure object generalizing the idea of a vector. In this way we are able to side step the vexing issue of defining precisely

What are Equal Sets?

What are equal sets? Subsets in math is an important concept for understanding the definition of equality in set theory. In this video we define equality in sets, which is fairly simple. One of the properties of equal sets is that if sets A and B are equal, then A is a subset of B and B is

Abstract : k-abelian singletons in connection with Gray codes for Necklaces. This work is based on [1]. We are interested in the equivalence classes induced by k-abelian equivalence, especially in the number of the classes containing only one element, k-abelian singletons. By characterizin

Some Small Ideas in Math: A Set of Measure Zero Versus a Set of First Category (Meager Sets)

There are a ton of different ways to define what it means for a set to be "small". Here, we will focusing on the difference between a set of measure zero versus a set of first category by using examples to demonstrate that they are different sizing methods. Depending on the context of the
