In mathematics, a projective plane has two possible definitions, one of them coming from linear algebra, and another (which is more general) coming from axiomatic geometry and finite geometry. The first definition quickly produces planes that are homogeneous spaces for some of the classical groups, including the real projective plane . The second is suitable for an exhaustive study of the simple incidence properties of plane geometry.

Algorithm
In mathematics, computing, and related subjects, an algorithm is an effective method for solving a problem using a finite sequence of instructions. Algorithms are used for calculation, data processing, and many other fields. Each algorithm is a list of well-defined instructions for completing a... -
Absolute value
In mathematics, the absolute value (or modulus) |a| of a real number a is a's numerical value without regard to its sign. So, for example, 3 is the absolute value of both 3 and −3. Generalizations of the absolute value for real numbers occur in a wide variety of mathematical settings. For example... -
Antisymmetric relation
In mathematics, a binary relation R on a set X is antisymmetric if, for all a and b in X or, equivalently, In mathematical notation, this is: or equally, An example of an antisymmetric relation is the subset relation: Or in words, if every element in A also is in B and all elements in B are in A,... -
Associativity
In mathematics, associativity is a property that a binary operation can have. It means that, within an expression containing two or more occurrences in a row of the same associative operator, the order that the operations are performed does not matter as long as the sequence of the operands is not... -
Algebra
Algebra is the branch of mathematics concerning the study of the rules of operations and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. Together with geometry, analysis, topology, combinatorics, and number theory, algebra is one... -
Bilinear operator
In mathematics, a bilinear operator is a function combining elements of two vector spaces to yield an element of a third vector space that is linear in each of its arguments. Matrix multiplication is an example. Let V, W and X be three vector spaces over the same base field F. A bilinear map is a... -
Combinatorics
Combinatorics is a branch of pure mathematics concerning the study of the enumeration of discrete, finite sets. It is related to many other areas of mathematics, such as algebra, probability theory, ergodic theory and geometry, as well as to applied subjects in computer science and statistical... -
Cauchy sequence
In mathematics, a Cauchy sequence, named after Augustin Cauchy, is a sequence whose elements become arbitrarily close to each other as the sequence progresses. To be more precise, by dropping enough (but still only a finite number of) terms from the start of the sequence, it is possible to make the... -
Cauchy distribution
The Cauchy–Lorentz Distribution, named after Augustin Cauchy and Hendrik Lorentz, is a continuous probability distribution. As a probability distribution, it is known as the Cauchy distribution, while among physicists, it is known as a Lorentz distribution, or a Lorentz(ian) function or the Breit... -
Elementary algebra
Elementary algebra is a fundamental and relatively basic form of algebra taught to students who are presumed to have little or no formal knowledge of mathematics beyond arithmetic. While in arithmetic only numbers and their arithmetical operations (such as +, −, ×, ÷) occur, in algebra one also...
