Arithmetic 2008/9 Schools Wikipedia Selection . Related subjects: Mathematics 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 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. 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 Plimpton 322, which appears to be a list of

69. Arithmetic Mean -- From Wolfram MathWorld The arithmetic mean of a set of values is the quantity commonly called the mean or the average. Given a set of samples {x_i}, the arithmetic mean is x^_=1/Nsum_(i=1)^Nx_i. http://mathworld.wolfram.com/ArithmeticMean.html

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Arithmetic Mean The arithmetic mean of a set of values is the quantity commonly called "the" mean or the average. Given a set of samples , the arithmetic mean is It can be computed in Mathematica using Mean list The arithmetic mean is the special case of the power mean and is one of the Pythagorean means When viewed as an estimator for the mean of the underlying distribution (known as the population mean ), the arithmetic mean of a sample is called the sample mean For a continuous distribution function , the arithmetic mean of the population, denoted , or and called the population mean of the distribution, is given by where is the expectation value . Similarly, for a discrete distribution The arithmetic mean satisfies and if and are independent statistics . The "sample mean," which is the mean estimated from a statistical sample, is an unbiased estimator for the population mean. Hoehn and Niven (1985) show that for any constant . For positive arguments, the arithmetic mean satisfies

73. Modular Arithmetic — An Introduction Modular arithmetic lets us state these results quite precisely, and it also provides a convenient language for similar but slightly more complex statements. http://www.math.rutgers.edu/~erowland/modulararithmetic.html

header("Modular Arithmetic"); Modular arithmetic is quite a useful tool in number theory. In particular, it can be used to obtain information about the solutions (or lack thereof) of a specific equation. This page gives a fairly detailed introduction. Another good introduction, in the form of an interactive tutorial, can be found in Part 2 of Math Alive: Cryptography Contents I. An Introductory Example II. Definition and Further Examples III. Properties of Congruence IV. Exercises I. An Introductory Example Everyone knows that set of integers can be broken up into the following two classes: There are certain generalizations we can make about the arithmetic of numbers based on which of these two classes they come from. For example, we know that the sum of two even numbers is even. The sum of an even number and an odd number is odd. The sum of two odd numbers is even. The product of two even numbers is even, etc. Modular arithmetic lets us state these results quite precisely, and it also provides a convenient language for similar but slightly more complex statements. In the above example, our modulus is the number 2. The modulus can be thought of as the number of classes that we have broken the integers up into. It is also the difference between any two "consecutive" numbers in a given class.

The Egyptian Zero Egyptian Counting Addition Subtraction ... Egyptian Fractions EYPTIAN COUNTING WITH HEIROGLYPHS These are the basic glyphs (symbols) used in Egypt for counting over 4000 years ago: Writing an integer consists of writing the number (from to 9) of the proper symbols to represent the integer. Thus, There is also a glyph which can translated as "equals" and a compact way of writing large glyphs, as shown below on the right, for two ways 35: in early Egypt Addition and subtraction were simple processes using the counting glyphs . To add two numbers, collect all symbols of similar type and replace a ten of one type by one of the next higher order. For example, adding 35 and 17: add Subtraction is a reversal of the process, if necessary replace a higher, so subtract Multiplication and Division Multiplication and Division were also simple processes using the counting glyphs . To multiply two numbers, all you needed to understand was the double or the half of an integer; i.e., the 2 times table.

Matrix arithmetic operations are defined by the rules of linear algebra. Array arithmetic operations are carried out element by element, and can be used with multidimensional arrays. The period character ( ) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs and are not used. Addition or unary plus. A+B adds A and B A and B must have the same size, unless one is a scalar. A scalar can be added to a matrix of any size. Subtraction or unary minus. A-B subtracts B from A A and B must have the same size, unless one is a scalar. A scalar can be subtracted from a matrix of any size. Matrix multiplication.
