aritmetički [ pridev ]

Koji spada u računanje, koji se može predstaviti ili rešiti brojevima, računski; aritmetička sredina nekih brojeva jeste zbir tih brojeva podeljen sbrojem od onoliko jedinica koliko je tih brojeva; up. geometrijska sredina; v. progresija.

ETYM Old Eng. arsmetike, Old Fren. arismetique, Latin arithmetica, from Greek arithmein to number, from arithmos number, prob. from same root as Eng. arm, the idea of counting coming from that of fitting, attaching.
The branch of mathematics dealing with the addition, subtraction, multiplication, and division of real numbers.
The branch of pure mathematics dealing with the theory of numerical calculations.
Branch of mathematics concerned with the study of numbers and their properties. The fundamental operations of arithmetic are addition, subtraction, multiplication, and division. Raising to powers (for example, squaring or cubing a number), the extraction of roots (for example, square roots), percentages, fractions, and ratios are developed from these operations.
Forms of simple arithmetic existed in prehistoric times. In China, Egypt, Babylon, and early civilizations generally, arithmetic was used for commercial purposes, records of taxation, and astronomy. During the Dark Ages in Europe, knowledge of arithmetic was preserved in India and later among the Arabs. European mathematics revived with the development of trade and overseas exploration. Hindu-Arabic numerals replaced Roman numerals, allowing calculations to be made on paper, instead of by the abacus.
The essential feature of this number system was the introduction of zero, which allows us to have a place–value system. The decimal numeral system employs ten numerals (0,1,2,3,4,5,6,7,8,and is said to operate in “base ten”. In a base-ten number, each position has a value ten times that of the position to its immediate right; for example, in the number the numeral 3 represents three units (ones), and the number 2 represents two tens. The Babylonians, however, used a complex base-sixty system, residues of which are found today in the number of minutes in each hour and in angular measurement (6 x degrees). The Mayas used a base-twenty system.
There have been many inventions and developments to make the manipulation of the arithmetic processes easier, such as the invention of logarithms by Scottish mathematician John Napier 16and of the slide rule in the period 1620–3Since then, many forms of ready reckoners, mechanical and electronic calculators, and computers have been invented.
Modern computers fundamentally operate in base two, using only two numerals (0,1), known as a binary system. In binary, each position has a value twice as great as the position to its immediate right, so that for example binary 1(or 111is equal to 7 in the decimal system, and binary 11(or 1111is equal to 1Because the main operations of subtraction, multiplication, and division can be reduced mathematically to addition, digital computers carry out calculations by adding, usually in binary numbers in which the numerals 0 and 1 can be represented by off and on pulses of electric current.
Modular or modulo arithmetic, sometimes known as residue arithmetic or clock arithmetic, can take only a specific number of digits, whatever the value. For example, in modulo 4 (mod the only values any number can take are or In this system, 7 is written as 3 mod and is also 3 mod Notice 3 is the residue, or remainder, when 7 or is divided by This form of arithmetic is often illustrated on a circle. It deals with events recurring in regular cycles, and is used in describing the functioning of gasoline engines, electrical generators, and so on. For example, in the mod 1the answer to a question as to what time it will be in five hours if it is now ten o’clock can be expressed + 5 = 3.
Properties of numbers.
Associative law.
All the properties of numbers may be deduced from this law, which states that the sum of a set of numbers is the same whatever the order of addition, and that the product of a set of numbers is the same whatever the order of multiplication.
Commutative law.
A special case of the associative law produces commutativity where there are only two numbers in the set. For example.
A + b = b + a.
Ab = ba.
Distributive law.
The distributive law for multiplication over addition states that, given a set of numbers a, b, c, . and a multiplier m.
M(a + b + c + .) = ma + mb + mc + .
For example.
9 × 1= (9 × 10+ (9 × 3+ (9 × 2).
The distributive law does not apply for addition over multiplication; for example.
7 + (3 × ą (7 + × (7 + 5).
Identities.
Zero is described as the identity for addition because adding zero to any number has no effect on that number.
N + 0 = 0 + n = n.
One is the identity for multiplication because multiplying any number by one leaves that number unchanged.
N × 1 = 1 × n = n.
Negatives.
Every number has a negative -n such that.
N + (-n) = 0.
Inverse.
Every number (except has an inverse 1/n such that.
N × 1/n = 1.
