Natural Number In mathematics , the NATURAL NUMBERS are those used for counting (as in "there are six coins on the table") and ordering (as in "this is the third largest city in the country"). In common language, words used for counting are "cardinal numbers " and words used for ordering are "ordinal numbers ". Some definitions, including the standard ISO 800002 , begin the natural numbers with 0 , corresponding to the NONNEGATIVE INTEGERS 0, 1, 2, 3, …, whereas others start with 1, corresponding to the POSITIVE INTEGERS 1 , 2 , 3 , …. Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the WHOLE NUMBERS, but in other writings, that term is used instead for the integers (including negative integers) [...More...]  "Natural Number" on: Wikipedia Yahoo 

Divisibility A DIVISIBILITY RULE is a shorthand way of determining whether a given integer is divisible by a fixed divisor without performing the division, usually by examining its digits. Although there are divisibility tests for numbers in any radix , or base, and they are all different, this article presents rules and examples only for decimal , or base 10, numbers. Martin Gardner Martin Gardner explained and popularized these rules in his September 1962 "Mathematical Games" column in Scientific American Scientific American [...More...]  "Divisibility" on: Wikipedia Yahoo 

History Of Ancient Egypt The HISTORY OF ANCIENT EGYPT spans the period from the early prehistoric settlements of the northern Nile Nile valley to the Roman conquest , in 30 BC. The Pharaonic Period is dated from the 32nd century BC , when Upper and Lower Egypt were unified, until the country fell under Macedonian rule , in 332 BC [...More...]  "History Of Ancient Egypt" on: Wikipedia Yahoo

Egyptian Hieroglyphs EGYPTIAN HIEROGLYPHS (/ˈhaɪrəˌɡlɪf, roʊ/ ) were the formal writing system used in Ancient Egypt Ancient Egypt . It combined logographic , syllabic and alphabetic elements, with a total of some 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts are derived from hieroglyphic writing; Meroitic was a late derivation from demotic. Use of hieroglyphic writing arises from protoliterate symbol systems in the Early Bronze Age , around the 32nd century BC ( Naqada III Naqada III ), with the first decipherable sentence written in the Egyptian language dating to the Second Dynasty (28th century BC) [...More...]  "Egyptian Hieroglyphs" on: Wikipedia Yahoo 

Imaginary Unit The IMAGINARY UNIT or UNIT IMAGINARY NUMBER (I) is a solution to the quadratic equation x2 + 1 = 0. Since there is no real number with this property, it extends the real numbers, and under the assumption that the familiar properties of addition and multiplication (namely closure , associativity , commutativity and distributivity ) continue to hold for this extension, the complex numbers are generated by including it. Imaginary numbers are an important mathematical concept, which extends the real number system ℝ to the complex number system ℂ, which in turn provides at least one root for every nonconstant polynomial P(x). (See Algebraic closure and Fundamental theorem of algebra .) The term "imaginary " is used because there is no real number having a negative square . There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero , which has one double square root [...More...]  "Imaginary Unit" on: Wikipedia Yahoo

Karnak The KARNAK TEMPLE COMPLEX, commonly known as KARNAK (/ˈkɑːr.næk/ ), comprises a vast mix of decayed temples , chapels, pylons, and other buildings. Construction at the complex began during the reign of Senusret I in the Middle Kingdom and continued into the Ptolemaic period , although most of the extant buildings date from the New Kingdom . The area around Karnak Karnak was the ancient Egyptian Ipetisut ("The Most Selected of Places") and the main place of worship of the eighteenth dynasty Theban Triad with the god Amun Amun as its head. It is part of the monumental city of Thebes . The Karnak Karnak complex gives its name to the nearby, and partly surrounded, modern village of ElKarnak, 2.5 kilometres (1.6 miles) north of Luxor Luxor [...More...]  "Karnak" on: Wikipedia Yahoo 

Partition (number Theory) In number theory and combinatorics , a PARTITION of a positive integer n, also called an INTEGER PARTITION, is a way of writing n as a sum of positive integers. Two sums that differ only in the order of their summands are considered the same partition. (If order matters, the sum becomes a composition .) For example, 4 can be partitioned in five distinct ways: 4 3 + 1 2 + 2 2 + 1 + 1 1 + 1 + 1 + 1 The orderdependent composition 1 + 3 is the same partition as 3 + 1, while the two distinct compositions 1 + 2 + 1 and 1 + 1 + 2 represent the same partition 2 + 1 + 1. A summand in a partition is also called a PART. The number of partitions of n is given by the partition function p(n). So p(4) = 5. The notation λ ⊢ n means that λ is a partition of n. Partitions can be graphically visualized with Young diagrams or Ferrers diagrams [...More...]  "Partition (number Theory)" on: Wikipedia Yahoo 

Ishango Bone The ISHANGO BONE is a bone tool , dated to the Upper Paleolithic Upper Paleolithic era. It is a dark brown length of bone, the fibula of a baboon , with a sharp piece of quartz affixed to one end, perhaps for engraving. It was first thought to be a tally stick , as it has a series of what has been interpreted as tally marks carved in three columns running the length of the tool. It has also been suggested that the scratches might have been to create a better grip on the handle or for some other nonmathematical reason. The Ishango bone was found in 1960 by Belgian Jean de Heinzelin de Braucourt while exploring what was then the Belgian Congo . It was discovered in the area of Ishango near the Semliki River [...More...]  "Ishango Bone" on: Wikipedia Yahoo 

Measurement MEASUREMENT is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of a measurement is dependent on the context and discipline. In the natural sciences and engineering , measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures . However, in other fields such as statistics as well as the social and behavioral sciences , measurements can have multiple levels , which would include nominal, ordinal, interval, and ratio scales. Measurement Measurement is a cornerstone of trade , science , technology , and quantitative research in many disciplines. Historically, many measurement systems existed for the varied fields of human existence to facilitate comparisons in these fields [...More...]  "Measurement" on: Wikipedia Yahoo 

Linguists LINGUISTICS is the scientific study of language , and involves an analysis of language form , language meaning , and language in context . The earliest activities in the documentation and description of language have been attributed to the 4th century BCE Indian grammarian Pāṇini Pāṇini , who wrote a formal description of the Sanskrit Sanskrit language in his Aṣṭādhyāyī. Linguists traditionally analyse human language by observing an interplay between sound and meaning . Phonetics is the study of speech and nonspeech sounds, and delves into their acoustic and articulatory properties. The study of language meaning , on the other hand, deals with how languages encode relations between entities, properties, and other aspects of the world to convey, process, and assign meaning, as well as manage and resolve ambiguity [...More...]  "Linguists" on: Wikipedia Yahoo 

List Of Continuityrelated Mathematical Topics In mathematics, the terms CONTINUITY, CONTINUOUS, and CONTINUUM are used in a variety of related ways. CONTINUITY OF FUNCTIONS AND MEASURES * Continuous function Continuous function . * Absolutely continuous function . * Absolute continuity of a measure with respect to another measure . * Continuous probability distribution . Sometimes this term is used to mean a probability distribution whose cumulative distribution function (c.d.f.) is (simply) continuous.

Discrete Mathematics DISCRETE MATHEMATICS is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers , graphs , and statements in logic – do not vary smoothly in this way, but have distinct, separated values. Discrete mathematics Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis . Discrete objects can often be enumerated by integers. More formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets (sets that have the same cardinality as subsets of the natural numbers, including rational numbers but not real numbers) [...More...]  "Discrete Mathematics" on: Wikipedia Yahoo 

Combinatorics COMBINATORICS is a branch of mathematics concerning the study of finite or countable discrete structures . Aspects of combinatorics include counting the structures of a given kind and size (enumerative combinatorics ), deciding when certain criteria can be met, and constructing and analyzing objects meeting the criteria (as in combinatorial designs and matroid theory), finding "largest", "smallest", or "optimal" objects (extremal combinatorics and combinatorial optimization ), and studying combinatorial structures arising in an algebraic context, or applying algebraic techniques to combinatorial problems (algebraic combinatorics ). Combinatorial problems arise in many areas of pure mathematics , notably in algebra , probability theory , topology , and geometry , and combinatorics also has many applications in mathematical optimization , computer science , ergodic theory and statistical physics [...More...]  "Combinatorics" on: Wikipedia Yahoo 

Primary School A PRIMARY SCHOOL (or ELEMENTARY SCHOOL in American English American English and often in Canadian English Canadian English ) is a school in which children receive primary or elementary education from the age of about five to twelve, coming after preschool and before secondary school . (In some countries there is an intermediate stage of middle school between primary and secondary education.) In most parts of the world, primary education is the first stage of compulsory education , and is normally available without charge, but may be offered in a feepaying independent school . The term GRADE SCHOOL is sometimes used in the US, although this term may refer to both primary education and secondary education . The term primary school is derived from the French école primaire, which was first used in 1802 [...More...]  "Primary School" on: Wikipedia Yahoo
