Division (mathematics) Division is one of the four basic operations of arithmetic, the others being addition, subtraction, and multiplication. The division of two natural numbers is the process of calculating the number of times one number is contained within another one.[1]:7 For example, in the picture on the right, the 20 apples are divided into four groups of five apples, meaning that twenty divided by five gives four, or four is the result of division of twenty by five. This is denoted as 20 / 5 = 4, 20 ÷ 5 = 4, or 20/5 = 4.[2] Division can be viewed either as quotition or as partition. In quotition, 20 ÷ 5 means the number of 5s that must be added to get 20. In partition, 20 ÷ 5 means the size of each of 5 parts into which a set of size 20 is divided. Division is the inverse of multiplication; if a × b = c, then a = c ÷ b, as long as b is not zero [...More...]  "Division (mathematics)" on: Wikipedia Yahoo 

Mathematical Software Mathematical software is software used to model, analyze or calculate numeric, symbolic or geometric data.[1] It is a type of application software which is used for solving mathematical problems or mathematical study. There are various views to what is the mathematics, so there is various views of the category of mathematical software which used for them, over from narrow to wide sense. A type of mathematical software (math library) also used by built in the part of an another scientific software. A most primary them (for example, to calculate elementary function by floating point arithmetic) may be in the category of mathematical software. They are often usually built in the general purpose systems as middleware. So to speak, mathematical software is not only an application software but also basis of the another scientific software [...More...]  "Mathematical Software" on: Wikipedia Yahoo 

Number Theory Number Number theory, or in older usage arithmetic, is a branch of pure mathematics devoted primarily to the study of the integers. It is sometimes called "The Queen of Mathematics" because of its foundational place in the discipline.[1] Number Number theorists study prime numbers as well as the properties of objects made out of integers (e.g., rational numbers) or defined as generalizations of the integers (e.g., algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (e.g., the Riemann zeta function) that encode properties of the integers, primes or other numbertheoretic objects in some fashion (analytic number theory) [...More...]  "Number Theory" on: Wikipedia Yahoo

Programming Language A programming language is a formal language that specifies a set of instructions that can be used to produce various kinds of output. Programming languages generally consist of instructions for a computer. Programming languages can be used to create programs that implement specific algorithms. The earliest known programmable machine that preceded the invention of the digital computer was the automatic flute player described in the 9th century by the brothers Musa in Baghdad, during the Islamic Golden Age.[1] From the early 1800s, "programs" were used to direct the behavior of machines such as Jacquard looms, music boxes and player pianos.[2] Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year [...More...]  "Programming Language" on: Wikipedia Yahoo

Logarithm In mathematics, the logarithm is the inverse operation to exponentiation, just as division is the inverse of multiplication. That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In the most simple case the logarithm counts repeated multiplication of the same factor; e.g., since 1000 = 10 × 10 × 10 = 103, the "logarithm to base 10" of 1000 is 3. More generally, exponentiation allows any positive real number to be raised to any real power, always producing a positive result, so the logarithm can be calculated for any two positive real numbers b and x where b is not equal to 1. The logarithm of x to base b, denoted logb (x) (or logb x when no confusion is possible), is the unique real number y such that by = x. For example, log2 64 = 6, as 64 = 26. The logarithm to base 10 (that is b = 10) is called the common logarithm and has many applications in science and engineering [...More...]  "Logarithm" on: Wikipedia Yahoo 

Nth Root In mathematics, an nth root of a number x, where n is usually assumed to be a positive integer, is a number r which, when raised to the power n yields x: r n = x , displaystyle r^ n =x, where n is the degree of the root. A root of degree 2 is called a square root and a root of degree 3, a cube root. Roots of higher degree are referred by using ordinal numbers, as in fourth root, twentieth root, etc. For example:3 is a square root of 9, since 32 = 9. −3 is also a square root of 9, since (−3)2 = 9.Any nonzero number, considered as complex number, has n different "complex roots of degree n" (nth roots), including those with zero imaginary part, i.e. any real roots. The root of 0 is zero for all degrees n, since 0n = 0 [...More...]  "Nth Root" on: Wikipedia Yahoo

Polynomial In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and nonnegative integer exponents of variables. An example of a polynomial of a single indeterminate x is x2 − 4x + 7. An example in three variables is x3 + 2xyz2 − yz + 1. Polynomials appear in a wide variety of areas of mathematics and science. For example, they are used to form polynomial equations, which encode a wide range of problems, from elementary word problems to complicated problems in the sciences; they are used to define polynomial functions, which appear in settings ranging from basic chemistry and physics to economics and social science; they are used in calculus and numerical analysis to approximate other functions [...More...]  "Polynomial" on: Wikipedia Yahoo 

Variable (mathematics) In elementary mathematics, a variable is a symbol, commonly an alphabetic character, that represents a number, called the value of the variable, which is either arbitrary, not fully specified, or unknown. Making algebraic computations with variables as if they were explicit numbers allows one to solve a range of problems in a single computation. A typical example is the quadratic formula, which allows one to solve every quadratic equation by simply substituting the numeric values of the coefficients of the given equation to the variables that represent them. The concept of a variable is also fundamental in calculus. Typically, a function y = f(x) involves two variables, y and x, representing respectively the value and the argument of the function [...More...]  "Variable (mathematics)" on: Wikipedia Yahoo 

Rational Number In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a nonzero denominator q.[1] Since q may be equal to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q (or blackboard bold Q displaystyle mathbb Q , Unicode ℚ);[2] it was thus denoted in 1895 by Giuseppe Peano Giuseppe Peano after quoziente, Italian for "quotient". The decimal expansion of a rational number always either terminates after a finite number of digits or begins to repeat the same finite sequence of digits over and over. Moreover, any repeating or terminating decimal represents a rational number. These statements hold true not just for base 10, but also for any other integer base (e.g [...More...]  "Rational Number" on: Wikipedia Yahoo

Closure (mathematics) A set has closure under an operation if performance of that operation on members of the set always produces a member of the same set; in this case we also say that the set is closed under the operation. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 displaystyle 12 is not a positive integer even though both 1 and 2 are positive integers [...More...]  "Closure (mathematics)" on: Wikipedia Yahoo
