In mathematics , an arithmeticgrouparithmetic subgroup in a linear algebraic group G defined over a number field K is a subgroup of G K that is commensurability mathematics commensurable with G O , where O is the ring of integers of K . Here two subgroups A and B of a group are commensurable when their Intersection set theory intersection has finite Index of a subgroup index in each of them. It can be shown that this condition depends only on G , not on a given matrix representation of G . Examples of arithmetic groups include therefore the groups GL sub n sub Z . The idea of arithmeticgroup is closely related to that of lattice discrete subgroup lattice in a Lie group . Lattices in that sense tend to be arithmetic, except in well defined circumstances. The exact relationship of the two concepts was established by the work of Grigory Margulis Margulis on superrigidity . The general theory of arithmetic groups was developed by Armand Borel and Harish Chandra the description of their fundamental domain s was in classical terms the reduction theory of algebraic form s.

The arithmetic IF statement has been for several decades a three way arithmetic Conditional programming conditional statement , starting from the very early version 1957 of Fortran , and including FORTRAN IV, FORTRAN 66 and FORTRAN 77. Unlike the Conditional programming logical IF statements seen in other languages, the Fortran statement defines three different branches depending on whether the result of an expression was negative, zero, or positive, in said order, written as IF expression negative,zero,positive While it was originally the only kind of IF statement provided in Fortran, the feature was used less and less frequently after the more powerful Conditional programming logical IF statements were introduced, and was finally labeled obsolescence obsolescent in Fortran 90. The arithmetic IF was also used in FOCAL programming language FOCAL .

In mathematical logic , Heyting arithmetic sometimes abbreviated HA is an axiomatization of arithmetic in accordance with the philosophy of intuitionism . It is named after Arend Heyting , who first proposed it. Heyting arithmetic adopts the axioms of Peano arithmetic PA , but uses intuitionistic logic as its rules of inference. In particular, the law of the excluded middle does not hold in general, though the induction axiom can be used to prove many specific cases. For instance, one can prove that nowrap 1 &forall x , y &isin N x y &or x &ne y is a theorem any two natural number s are either equal to each other, or not equal to each other . In fact, since is the only Predicate mathematics predicate symbol in Heyting arithmetic, it then follows that, for any quantifier free formula p , nowrap 1 &forall x , y , z , &hellip &isin N p &or ¬ p is a theorem where x , y , z &hellip are the free variables in p . Kurt G del studied the relationship between Heyting arithmetic and Peano arithmetic. He used the G del Gentzen negative translation to prove in 1933 that if HA is consistent, then PA is also consistent. Heyting arithmetic should not be confused with Heyting algebra s, which are the intuitionistic analogue of Boolean algebra structure Boolean algebras .

In mathematics , an arithmetic progression AP or arithmetic sequence is a sequence of number s such that the difference between the consecutive terms is constant.

Saturation arithmetic is a version of arithmetic in which all operations such as addition and multiplication are limited to a fixed range between a minimum and maximum value. If the result of an operation is greater than the maximum it is set clamped to the maximum, while if it is below the minimum it is clamped to the minimum. The name comes from how the value becomes saturated once it reaches the extreme values further additions to a maximum or subtractions from a minimum will not change the result. For example, if the valid range of values is from 100 to 100, the following operations produce ... fail in saturation arithmetic.

The Treviso Arithmetic , or Arte dell Abbaco , is an anonymous textbook in commercial arithmetic written in vernacular Venetian and published in Treviso , Italy in 1478. The author tells us the reason for writing this textbook ref David Eugene Smith The First Printed Arithmetic Treviso, 1478 , Isis , 6 1924 311 331, at p. 314 ref Blockquote I have often been asked by certain youths in whom I have much interest, and who look forward to mercantile pursuits, to put into writing the fundamental principles of arithmetic, commonly called abacus. The Treviso Arithmetic is the earliest known printed mathematics book in the West, and one of the first printed European textbooks dealing with a science. The Arithmetic as an early printed book There appears to have been only one edition of the work. David Eugene Smith translated parts of the Treviso Arithmetic for educational purposes in 1907.

unreferenced date July 2011 In elementary arithmetic a carry is a digit that is transferred from one column of digits to another column of more significant digits during a calculation algorithm . When used in subtraction the operation is called a borrow . It is a central part of traditional mathematics , but is often omitted from curricula based on reform mathematics , which do not emphasize any specific method to find a correct answer. Manual arithmetic A typical example of carry is in the following pencil and paper addition 27 59 86 7 9 16, and the digit 1 number 1 is the carry. The opposite is a borrow , as in sup 1 sup 47 19 28 Here, 7 9 2, so try 10 9 7 8, and the 10 is got by taking borrowing 1 from the next digit to the left. There are two ways in which this is commonly taught The ten is moved from the next digit left, leaving in this example 3 1 in the tens column. According to this method, the term borrow is a misnomer , since the ten is never paid back. The ten is copied from the next digit left, and then paid back by adding it to the subtrahend in the column from which it was borrowed , giving in this example 4 1 1 in the tens column. Mathematics education globalize USA section date December 2010 Traditionally, carry is taught in the addition of multi digit numbers in the 2nd or late first year of elementary school. However since the late 20th century, many widely adopted curricula developed in the United States such as TERC omitted instruction of the traditional carry method in favor of invented arithmetic methods, and methods using coloring, manipulatives, and charts ....

Introduction to Arithmetic Arithmetike eisagoge was written by Nicomachus almost two thousand years ago, and contains both philosophical prose and very basic mathematical ideas. Nicomachus refers to Plato quite often, and wrote about how philosophy can only be possible if one knows enough about mathematics . This is the only complete book of his that survived to our day. Nicomachus describes how natural numbers and basic mathematical ideas are eternal and unchanging, and in an abstract realm.
