Arithmetic From Wikipedia, the free encyclopedia Jump to: navigation search Arithmetic tables for children, Lausanne, 1835 Arithmetic or arithmetics (from the Greek word = number) is the oldest and most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple day-to-day counting to advanced science and business calculations. In common usage, the word refers to a branch of (or the forerunner of) mathematics which records elementary properties of certain operations on numbers . Professional mathematicians sometimes use the term (higher) arithmetic when referring to number theory , but this should not be confused with elementary arithmetic Contents History Decimal arithmetic Arithmetic operations Addition (+) ... edit History The prehistory of arithmetic is limited to a very small number of small artifacts indicating a clear conception of addition and subtraction, the best-known being the Ishango bone from central Africa , dating from somewhere between 18,000 and 20,000 BC. Arithmetic we use today came from India along with the Hindu Arabic numerals. Earlier times it was known as "Method of the Hindus" or in Latin "Modus Indorum". It is clear that the Babylonians had solid knowledge of almost all aspects of elementary arithmetic by 1800 BC, although historians can only guess at the methods utilized to generate the arithmetical results - as shown, for instance, in the clay tablet

Search Site Algebra Applied Mathematics Calculus and Analysis ... Culinary Terminology Arithmetic Arithmetic is the branch of mathematics dealing with integers or, more generally, numerical computation. Arithmetical operations include addition congruence calculation, division factorization multiplication power computation, root extraction , and subtraction . Arithmetic was part of the quadrivium taught in medieval universities. A mnemonic for the spelling of "arithmetic" is "a rat in the house may eat the ice cream." The branch of mathematics known as number theory is sometimes known as higher arithmetic Modular arithmetic is the arithmetic of congruences Floating-point arithmetic is the arithmetic performed on real numbers by computers or other automated devices using a fixed number of bits. The fundamental theorem of arithmetic , also called the unique factorization theorem, states that any positive integer can be represented in exactly one way as a product of primes The , which is a fundamental result in model theory , establishes the existence of "nonstandard" models of arithmetic.

Vector Arithmetic Are these the arrows of outrageous fortune of which we have heard?... In measuring position by distance and direction we used a line with an arrowhead on it. This representation of position is called a "vector". Just as there is an arithmetic of numbers, there is an arithmetic of vectors. We are going to be interested in motion of particles and have already said that motion is change in position over time. To get a change in a number it is customary to subtract the initial value from the final. To get a change in position we will use the same technique, subtracting the starting position from the ending. So how would you subtract two positions? Well it is most convenient to think of the positions as vectors to do this. We have identified a line segment with direction and magnitude as a vector. If V V To add vectors there are two techniques available, geometric addition and algebraic addition. Both yield the same result. The choice of which technique to use in adding vectors depends on the application and is a matter of convenience. First we will discuss geometric vector addition. Since a vector is defined by its magnitude and direction, changing its location in our reference frame without changing its direction or magnitude leaves it the same vector. We are free to relocate a vector anywhere in our space where we find it convenient. To add vectors geometrically we just place the tail of one at the head of the other. The sum then is a vector from the tail of the first vector to the head of the last. Run the

Its meaning, however, has not been uniform in mathematical usage. An eminent German mathematician, Carl Friedrich Gauss , in Disquisitiones Arithmeticae (1801), and certain modern-day mathematicians have used the term to include more advanced topics.

General Decimal Arithmetic FAQ Bibliography Arithmetic specification Formats (encodings) ... decNumber C implementation and C++ implementation DFPAL Testcases Summary ... Decimal web links Most computers today support binary floating-point in hardware. While suitable for many purposes, binary floating-point arithmetic should not be used for financial, commercial, and user-centric applications or web services because the decimal data used in these applications cannot be represented exactly using binary floating-point. (See the Frequently Asked Questions pages for an explanation of this, and several examples.) The problems of binary floating-point can be avoided by using base 10 (decimal) exponents and preserving those exponents where possible. This site describes a decimal arithmetic which achieves the necessary results and is suitable for both hardware and software implementation. It brings together the relevant concepts from a number of ANSI, IEEE, ECMA, and ISO standards

A Research Training Network of the European Union Overview Partners Programme Positions Activities Project overview Developing powerful methods taken from geometry to study the arithmetical properties of algebraic equations Algebraic equations and their arithmetical properties have interested mankind since antiquity. One has only to think of the works of Pythagoras and Diophantus, which were a milestone in their time. For many centuries such problems have fascinated both serious mathematicians (Fermat, Gauss, ...) and amateurs alike. However, developments in recent years have transformed the subject into one of the central areas of mathematical research, which has relations with, or applications to, virtually every mathematical field, as well as an impact to contemporary everyday life (for example, the use of prime numbers and factorisation for encoding "smart" cards). The classical treatment of equations by analysis and geometry in the realm of complex numbers in this century has found a counterpart, in the similar theories over finite and p -adic fields, which have particular significance for arithmetic questions.
