	Numbers [Definition]
		Grammatical number is distinct from the use of numerals to specify the exact quantify of a noun; number is usually vague.
		Algebraic numbers In mathematics, an algebraic number relative to a field F is any element x of a given field K containing F such that x is a solution of a polynomial equation of the form...
		Numbers should be distinguished from numerals A numeral is a symbol or group of symbols that represents a number.

	Hyperreal Number [Definition] (Site not responding. Last check: 2007-11-06)
		Rational numbers In mathematics, a rational number (or informally fraction) is a ratio of two integers, usually written as the vulgar fraction a/b, where b is not zero.
		Hypercomplex numbers In mathematics, hypercomplex numbers are extensions of the complex numbers constructed by means of abstract algebra, such as quaternions, tessarines, coquaternions, octonions, biquaternions and sedenions....
		Surreal numbers In mathematics, the surreal numbers are a field containing the real numbers as well as infinite and infinitesimal numbers, respectively larger or smaller in absolute value than any positive real number, and therefore the surreals are algebraically similiar to superreal numbers and hyperreal numbers.

		Rational numbers are made up of all numbers that can be expressed as a fraction of integers, though the whole numbers are rational, despite not being fractions, because they can be understood to have been divided by 1.
		While (most) real numbers have infinitely long expansions to the right of the decimal point, one can also try to allow for infinitely long expansions to the left in base p, where p is a prime, leading to the p-adic numbers.
		The arithmetical operations of numbers, such as addition, subtraction, multiplication and division, are generalized in the branch of mathematics called abstract algebra ; one obtains the groups, rings and fields.

	Superreal number - Wikipedia, the free encyclopedia
		The superreal numbers compose a more inclusive category than hyperreal number.
		Then the factor algebra A = C(X)/P is by definition an integral domain which is a real algebra and which can be seen to be totally ordered.
		If the prime ideal P is a maximal ideal, then F is a field of hyperreal numbers.

	Natural number (Site not responding. Last check: 2007-11-06)
		Natural numbers have two main purposes: they can be used for counting ("there are 3 apples on the table"), or they can be used for ordering ("this is the 3rd largest city in the country").
		Properties of the natural numbers related to divisibility, such as the distribution of prime numbers, are studied in number theory.
		Two generalizations of natural numbers arise from the two uses: ordinal numbers are used to describe the position of an element in a ordered sequence and cardinal numbers are used to specify the size of a given set.

	Ordinal number (Site not responding. Last check: 2007-11-06)
		In mathematics, ordinal numbers are an extension of the natural numbers to accommodate infinite sequences, introduced by Georg Cantor in 1897.
		A natural number can be used for two purposes: to describe the size of a set, or to describe the position of an element in a sequence.
		The size aspect leads to cardinal numbers, which were also discovered by Cantor, while the position aspect is generalized by the ordinal numbers described here.

		In mathematics, the real numbers are intuitively defined as number s that are in one-to-one correspondence with the points on an infinite line —the number line.
		Real numbers may be rational or irrational ; algebraic or transcendental ; and positive, negative, or zero.
		Ordered fields extending the reals are the hyperreal number s and the surreal number s; both of them contain infinitesimal and infinitely large numbers and thus are not Archimedean.

		In mathematics, the real numbers are intuitively defined as numbers that are in one-to-one correspondence with the points on an infinite line —the number line.
		Writing them as decimal fractions (which are rational numbers that could be written as ratios, with an explicit denominator) is not only more compact, but to some extent conveys the sense of an underlying real number.
		Occasionally, formal elements +∞ and -∞ are added to the reals to form the extended real number line, a compact space which is not a field but retains many of the properties of the real numbers.

		Like the natural numbers, Z is closed under the operations of addition and multiplication, that is, the sum and product of any two integers is an integer.

	Rational number (Site not responding. Last check: 2007-11-06)
		The decimal expansion of a rational number is eventually periodic (in the case of a finite expansion the zeroes which implicitly follow it form the periodic part).
		Conversely, if the expansion of a number for one base is periodic, it is periodic for all bases and the number is rational.
		The rational numbers are an important example of a space which is not locally compact.

	The Ultimate Hyperreal number Dog Breeds Information Guide and Reference (Site not responding. Last check: 2007-11-06)
		In mathematics, particularly in non-standard analysis and mathematical logic, hyperreal numbers or nonstandard reals (usually denoted as * R) denote an ordered field which is a proper extension of the ordered field of real numbers R and which satisfies the transfer principle.
		The application of hyperreal numbers and in particular the transfer principle to problems of analysis is called nonstandard analysis ; some find it more intuitive than standard real analysis.
		Nonetheless these concepts were from the beginning seen as suspect, notably by Berkeley, and when in the 1800s calculus was put on a firm footing through the development of the epsilon-delta definition of a limit by Cauchy, Weierstrass and others, they were largely abandoned.

		This number is equivalent with the ordinal number with the same name.

		The surreal numbers are an example of what is sometimes called a Field, meaning a proper class on which there is defined an addition, multiplication and multiplicative inverse which satisfy all of the axioms of a field except for the fact that the elements form a proper class but not a set.
		With that caveat they are an ordered field containing the real numbers as well as infinite and infinitesimal numbers, respectively larger or smaller in absolute value than any positive real number, and therefore the surreals are algebraically similiar to superreal numbers and hyperreal numbers.

		The subset of rational numbers having a finite decimal representation are called decimal fraction s or decimal numbers, sometimes denoted by D.
		Iterating the adjunction of imaginary unit s allows to extend complex numbers to quaternion s H, losing commutativity of multiplication, and then to octonion s, losing associativity and thus leaving the category of associative division algebra s.
		Numbers should be distinguished from numeral s, which are (combinations of) symbol s used to represent numbers.

	The Ultimate Field (mathematics) Dog Breeds Information Guide and Reference
		Fields are important objects of study in algebra since they provide the proper generalization of number domains, such as the sets of rational numbers, real numbers, or complex numbers.
		For instance, Q ( i) is the subfield of the complex numbers C consisting of all numbers of the form a+bi where both a and b are rational numbers.
		The surreal numbers form a Field containing the reals, and would be a field except for the fact that they are a proper class, not a set.

		The hyperreals are to be defined in such a way that every true first-order logic statement that uses basic arithmetic (the natural numbers, plus, times, comparison) and quantifies only over the real numbers is also true in a reinterpreted form if we presume that it quantifies over hyperreal numbers.
		A consistent choice of index sets that matter is given by any free ultrafilter U on the natural number s; these can be characterized as ultrafilters which do not contain any finite sets.
