Set theory , branch of mathematics that deals with the properties of well-defined collections of objects, which may or may not be of a mathematical nature, such as numbers or functions. The theory is less valuable in direct application to ordinary experience than as a basis for precise and adaptable terminology for the definition of complex and sophisticated mathematical concepts. Between the years and , the German mathematician and logician Georg Cantor created a theory of abstract sets of entities and made it into a mathematical discipline. This theory grew out of his investigations of some concrete problems regarding certain types of infinite sets of real numbers.

Starting from infancy and continuing throughout the preschool period, they develop a base of skills, concepts, and misconceptions about numbers and mathematics. Chapter 4 laid out a framework for describing mathematical proficiency in terms of a set of interwoven strands. During the last 25 years, developmental psychologists and mathematics educators have made substantial progress in understanding the ways in which these strands interact.

Between the years and , the German mathematician and logician Georg Cantor created a theory of abstract sets of entities and made it into a mathematical discipline. This theory grew out of his investigations of some concrete problems regarding certain types of infinite sets of real numbers. A set, wrote Cantor, is a collection of definite, distinguishable objects of perception or thought conceived as a whole.
Mathematical logic , also called formal logic , is a subfield of mathematics exploring the formal applications of logic to mathematics. It bears close connections to metamathematics , the foundations of mathematics , and theoretical computer science. Mathematical logic is often divided into the fields of set theory , model theory , recursion theory , and proof theory. These areas share basic results on logic, particularly first-order logic , and definability. In computer science particularly in the ACM Classification mathematical logic encompasses additional topics not detailed in this article; see Logic in computer science for those.

Set theory is a branch of mathematical logic that studies sets , which informally are collections of objects. Although any type of object can be collected into a set, set theory is applied most often to objects that are relevant to mathematics. The language of set theory can be used to define nearly all mathematical objects. The modern study of set theory was initiated by Georg Cantor and Richard Dedekind in the s.
Some clarifications and mathematical definitions which are concerned with the many fundamental concepts of computability theory based directly on the computer field, are presented.
