In mathematics, the term undefined refers to a value, function, or other expression that cannot be assigned a meaning within a specific formal system. [ 1 ] Attempting to assign or use an undefined value within a particular formal system, may produce contradictory or meaningless results within that system.
Although applicable to any area of mathematics, geometry is the branch of elementary mathematics in which this method has most extensively been successfully applied. [1] There are several components of an axiomatic system. [2] Primitives (undefined terms) are the most basic ideas. Typically they include objects and relationships.
The necessity for primitive notions is illustrated in several axiomatic foundations in mathematics: Set theory : The concept of the set is an example of a primitive notion. As Mary Tiles writes: [ 6 ] [The] 'definition' of 'set' is less a definition than an attempt at explication of something which is being given the status of a primitive ...
In mathematics and logic, an axiomatic system is any set of primitive notions and axioms to logically derive theorems.A theory is a consistent, relatively-self-contained body of knowledge which usually contains an axiomatic system and all its derived theorems.
Polynomial rings occur and are often fundamental in many parts of mathematics such as number theory, commutative algebra, and algebraic geometry. In ring theory , many classes of rings, such as unique factorization domains , regular rings , group rings , rings of formal power series , Ore polynomials , graded rings , have been introduced for ...

A lesson learned by mathematics in the last 150 years is that it is useful to strip the meaning away from the mathematical assertions (axioms, postulates, propositions, theorems) and definitions. One must concede the need for primitive notions, or undefined terms or concepts, in any study. Such abstraction or formalization makes mathematical ...
Euclidean geometry is a mathematical system attributed to ancient Greek mathematician Euclid, which he described in his textbook on geometry, Elements.Euclid's approach consists in assuming a small set of intuitively appealing axioms (postulates) and deducing many other propositions from these.
