As of my last update in October 2023, I'm not familiar with any widely recognized concept or product called "Booleo." It's possible that it could refer to a brand, product, service, or term that has emerged or become popular after that date, or it could be a niche term that isn't widely documented.
Percentage is a way of expressing a number as a fraction of 100. It is often used to compare proportions or to describe how much of a whole is represented by a given quantity. The symbol for percentage is "%". For example, if you have 25 out of 100 apples, you can express this as 25%. This means that 25 apples represent 25 percent of the total 100 apples.
In electronics, an adder is a digital circuit that performs addition of binary numbers. Adders are fundamental building blocks in arithmetic logic units (ALUs) and are widely used in various computing systems, such as microprocessors and digital signal processors. There are several types of adders, each with different characteristics and purposes: 1. **Half Adder**: A basic adder that adds two single-bit binary numbers. It has two outputs: the sum (S) and the carry (C).
Chunking is a cognitive strategy often used in learning and memory that involves breaking down information into smaller, more manageable units or "chunks." This technique is particularly useful when dealing with large amounts of data, as it makes it easier to process, understand, and remember the information. In the context of division or mathematics, chunking can refer to a method of dividing numbers by breaking the problem down into simpler, smaller parts.
Real numbers are a set of numbers that include all the numbers on the number line. This set encompasses several categories of numbers, including: 1. **Natural Numbers**: The positive integers starting from 1 (e.g., 1, 2, 3, ...). 2. **Whole Numbers**: Natural numbers plus zero (e.g., 0, 1, 2, 3, ...).
The term "tanhc" does not seem to refer to a well-known mathematical function or concept. However, it could be a typographical error or a misunderstanding related to the "tanh" function.
The Schröder–Bernstein theorem is a fundamental result in set theory concerning the sizes of sets, particularly in relation to their cardinalities. It states that if there are injective (one-to-one) functions between two sets \( A \) and \( B \) such that: 1. There exists an injective function \( f: A \to B \) (embedding of \( A \) into \( B \)), 2.
A Suslin cardinal is a large cardinala concept in set theory—characterized by certain properties related to the structure of the continuum and well-ordering. Specifically, a cardinal \( \kappa \) is called a Suslin cardinal if: 1. \( \kappa \) is uncountable. 2. There is a family of subsets of \( \kappa \) that is of size \( \kappa \), with each subset being a subset of \( \kappa \).
The Von Neumann cardinal assignment, also known as the Von Neumann cardinal numbers, is a way of representing cardinal numbers (which measure the size of sets) using well-defined sets in the context of set theory. In this framework, each cardinal number is identified with the set of all smaller cardinals. ### Definition: - A **cardinal number** is defined using ordinals in set theory.
A table of Gaussian integer factorizations provides a systematic way to represent the prime factorization of numbers within the domain of Gaussian integers. Gaussian integers are complex numbers of the form \(a + bi\), where \(a\) and \(b\) are integers and \(i\) is the imaginary unit, satisfying \(i^2 = -1\).
Numbering in sports refers to the system of assigning specific numbers to players, which helps identify them during games. This practice serves several purposes: 1. **Player Identification**: Numbers make it easier for fans, commentators, and officials to recognize and differentiate players on the field or court. Each player usually wears a unique number on their jersey. 2. **Team Organization**: Numbers can indicate positions or roles within a team.
Numerology is a belief system that considers the mystical significance of numbers and their influence on human life and events. It posits that numbers are not merely mathematical symbols but have inherent meanings and vibrations that can affect one's personality, destiny, and experiences. Practitioners of numerology analyze various numerical components related to individuals, such as their birth date and name, to derive insights about their character, life path, and potential future.
A fuzzy number is a concept in fuzzy set theory that represents quantities with uncertainty or vagueness. Unlike traditional crisp numbers, which have a precise value, fuzzy numbers allow for the representation of values that are not precisely defined, which is particularly useful in situations where information is imprecise or uncertain. A fuzzy number is typically characterized by a membership function that defines how each element in the universal set corresponds to a degree of membership within the fuzzy set.
A regnal number is a numerical designation given to a specific monarch within a particular royal lineage or dynasty. It helps to distinguish monarchs who share the same name by assigning them sequential numbers. For example, "Henry VIII" refers to the eighth king named Henry in English history. Regnal numbers are commonly used in monarchical systems and are often seen in historical contexts, official documents, and in the naming of kings and queens to provide clarity and avoid confusion among rulers with identical names.
Elwyn Berlekamp is a distinguished mathematician and computer scientist known for his work in game theory, combinatorial games, and coding theory. He is particularly recognized for his contributions to the field of combinatorial game theory, where he has developed strategies and mathematical frameworks for analyzing games like Nim and Go. Berlekamp is also notable for his involvement in developing error-correcting codes, which have significant applications in telecommunications and data storage.
A bijective proof is a type of mathematical argument that demonstrates the equivalence of two sets by establishing a bijection (a one-to-one and onto correspondence) between them. In other words, a bijective proof shows that there is a direct pairing between the elements of two sets in such a way that each element in one set matches exactly one element in the other set, and vice versa.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
