In mathematics, a **set** is a well-defined collection of distinct objects, considered as an object in its own right. The objects in a set are called the **elements** or **members** of the set. Sets can contain any type of objects, including numbers, symbols, other sets, or even more abstract entities. ### Notation: - A set is typically denoted using curly braces.
A mathematical object is a fundamental entity or concept studied in mathematics. These objects can take many forms and can include: 1. **Numbers**: Integers, rational numbers, real numbers, complex numbers, etc. 2. **Sets**: Collections of objects, which can include numbers, points in space, or other mathematical entities. 3. **Functions**: Mappings from one set of numbers (or other objects) to another, capturing the idea of a relationship between quantities.
Infinity is a concept that describes something without any limit or bound. It is often used in mathematics, physics, philosophy, and other fields to express ideas that go beyond finite quantities. Here are a few contexts in which infinity is commonly discussed: 1. **Mathematics**: In calculus, infinity describes the behavior of functions as they approach unbounded values. For instance, the limit of a function can tend towards infinity, which indicates that the function grows without bound.

They provide a framework for understanding and formalizing various mathematical concepts. Here are some common types of mathematical structures: 1. **Sets**: The most fundamental concept in mathematics, a set is simply a collection of distinct objects, considered as an object in its own right.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
