Archimedes used the method of exhaustion to approximate the value of pi. The history of mathematics can be seen as an ever-increasing series of abstractions. The first abstraction, which is shared by many animals,  was probably that of numbers: Many early texts mention Pythagorean triples and so, by inference, the Pythagorean theorem seems to be the most ancient and widespread mathematical development after basic arithmetic and geometry.
Each area has a distinct focus, although many techniques and results are shared among multiple areas. The borderlines amongst these fields, and the lines separating mathematical logic and other fields of mathematics, are not always sharp. The method of forcing is employed in set theory, model theory, and recursion theory, as well as in the study of intuitionistic mathematics.
The mathematical field of category theory uses many formal axiomatic methods, and includes the study of categorical logicbut category theory is not ordinarily considered a subfield of mathematical logic. Because of its applicability in diverse fields of mathematics, mathematicians including Saunders Mac Lane have proposed category theory as a foundational system for mathematics, independent of set theory.
These foundations use toposeswhich resemble generalized models of set theory that may employ classical or nonclassical logic. History[ edit ] Mathematical logic emerged in the midth century as a subfield of mathematics, reflecting the confluence of two traditions: The first half of the 20th century saw an explosion of fundamental results, accompanied by vigorous debate over the foundations of mathematics.
History of logic Theories of logic were developed in many cultures in history, including ChinaIndiaGreece and the Islamic world.
In 18th-century Europe, attempts to treat the operations of formal logic in a symbolic or algebraic way had been made by philosophical mathematicians including Leibniz and Lambertbut their labors remained isolated and little known.
Charles Sanders Peirce built upon the work of Boole to develop a logical system for relations and quantifiers, which he published in several papers from to Gottlob Frege presented an independent development of logic with quantifiers in his Begriffsschriftpublished ina work generally considered as marking a turning point in the history of logic.
Frege's work remained obscure, however, until Bertrand Russell began to promote it near the turn of the century. The two-dimensional notation Frege developed was never widely adopted and is unused in contemporary texts. This work summarized and extended the work of Boole, De Morgan, and Peirce, and was a comprehensive reference to symbolic logic as it was understood at the end of the 19th century.
Foundational theories[ edit ] Concerns that mathematics had not been built on a proper foundation led to the development of axiomatic systems for fundamental areas of mathematics such as arithmetic, analysis, and geometry. In logic, the term arithmetic refers to the theory of the natural numbers.
Peano was unaware of Frege's work at the time. Around the same time Richard Dedekind showed that the natural numbers are uniquely characterized by their induction properties.

Primes to Ideal for middle school introduction or remedial review.; The Hundreds Board is the MOST VALUABLE manipulatives in elementary mathmatics. Mathematical logic is a subfield of mathematics exploring the applications of formal logic to mathematics. It bears close connections to metamathematics, the foundations of mathematics, and theoretical computer science. The unifying themes in mathematical logic include the study of the expressive power of formal systems and the deductive power of formal proof systems.
Dedekind proposed a different characterization, which lacked the formal logical character of Peano's axioms. Dedekind's work, however, proved theorems inaccessible in Peano's system, including the uniqueness of the set of natural numbers up to isomorphism and the recursive definitions of addition and multiplication from the successor function and mathematical induction.
In the midth century, flaws in Euclid's axioms for geometry became known Katzp. In addition to the independence of the parallel postulateestablished by Nikolai Lobachevsky in Lobachevskymathematicians discovered that certain theorems taken for granted by Euclid were not in fact provable from his axioms.
Among these is the theorem that a line contains at least two points, or that circles of the same radius whose centers are separated by that radius must intersect. Hilbert developed a complete set of axioms for geometrybuilding on previous work by Pasch The success in axiomatizing geometry motivated Hilbert to seek complete axiomatizations of other areas of mathematics, such as the natural numbers and the real line.
This would prove to be a major area of research in the first half of the 20th century. The 19th century saw great advances in the theory of real analysisincluding theories of convergence of functions and Fourier series.
Mathematicians such as Karl Weierstrass began to construct functions that stretched intuition, such as nowhere-differentiable continuous functions. Previous conceptions of a function as a rule for computation, or a smooth graph, were no longer adequate.
Weierstrass began to advocate the arithmetization of analysiswhich sought to axiomatize analysis using properties of the natural numbers.
Cauchy in defined continuity in terms of infinitesimals see Cours d'Analyse, page InDedekind proposed a definition of the real numbers in terms of Dedekind cuts of rational numbers Dedekinda definition still employed in contemporary texts.
Georg Cantor developed the fundamental concepts of infinite set theory. His early results developed the theory of cardinality and proved that the reals and the natural numbers have different cardinalities Cantor Mathematical logic is a subfield of mathematics exploring the applications of formal logic to mathematics.
