| Equality: A. In mathematics, equality is a relationship between two quantities or expressions, asserting that they have the same value. It is written using the equals sign (=). For example, 2+3=5 and x=2x/2 are both equalities. The concept is also used in many other fields, such as physics, engineering, and computer science. - B. Equality in politics is the idea that all people are equal in fundamental worth or moral status. This means that all people deserve to be treated with respect and dignity, regardless of their race, gender, religion, social class, or any other factor. See also Equal sign, Equations._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
