Natural Number
In mathematics, the natural numbers are those numbers 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"). Numbers used for counting are called ''Cardinal number, cardinal numbers'', and numbers used for ordering are called ''Ordinal number, ordinal numbers''. Natural numbers are sometimes used as labels, known as ''nominal numbers'', having none of the properties of numbers in a mathematical sense (e.g. sports Number (sports), jersey numbers). Some definitions, including the standard ISO/IEC 80000, ISO 80000-2, begin the natural numbers with , corresponding to the non-negative integers , whereas others start with , corresponding to the positive integers Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the whole numbers, while in other writings, that term is used instead for the integers (including negative integers).

Magic Square
In recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. The 'order' of the magic square is the number of integers along one side (''n''), and the constant sum is called the ' magic constant'. If the array includes just the positive integers 1,2,...,n^2, the magic square is said to be 'normal'. Some authors take magic square to mean normal magic square. Magic squares that include repeated entries do not fall under this definition and are referred to as 'trivial'. Some well-known examples, including the Sagrada Família magic square and the Parker square are trivial in this sense. When all the rows and columns but not both diagonals sum to the magic constant this gives a ''semimagic square (sometimes called orthomagic square). The mathematical study of magic squares typically deals with their construction, classification, and enumeration. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factorial
In mathematics, the factorial of a non-negative denoted is the product of all positive integers less than or equal The factorial also equals the product of n with the next smaller factorial: \begin n! &= n \times (n-1) \times (n-2) \times (n-3) \times \cdots \times 3 \times 2 \times 1 \\ &= n\times(n-1)!\\ \end For example, 5! = 5\times 4! = 5 \times 4 \times 3 \times 2 \times 1 = 120. The value of 0! is 1, according to the convention for an empty product. Factorials have been discovered in several ancient cultures, notably in Indian mathematics in the canonical works of Jain literature, and by Jewish mystics in the Talmudic book '' Sefer Yetzirah''. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, where its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there In mathematical analysis, factorials are used in power series for the exponential function an ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...

Musical Note
In music, a note is the representation of a musical sound. Notes can represent the Pitch (music), pitch and Duration (music), duration of a sound in musical notation. A note can also represent a pitch class. Notes are the building blocks of much written music: musical analysis#Discretization, discretizations of musical phenomena that facilitate performance, comprehension, and musical analysis, analysis. The term ''note'' can be used in both generic and specific senses: one might say either "the piece 'Happy Birthday to You' begins with two notes having the same pitch", or "the piece begins with two repetitions of the same note". In the former case, one uses ''note'' to refer to a specific musical event; in the latter, one uses the term to refer to a class of events sharing the same pitch. (See also: Key signature names and translations.) Two notes with fundamental frequency, fundamental frequencies in a ratio equal to any integer power of two (e.g., half, twice, or four times ...

Telephone Numbers In Bangladesh
The country calling code for Bangladesh is +880 The dial plan type in Bangladesh is closed, and "0" is the Trunk prefix. When dialling a Bangladesh number from inside Bangladesh, the format is: "0 – Area/operator code (X) – subscriber number (N)" When dialling a Bangladesh number from outside Bangladesh, the format is: "+880 – Area/operator code (X) – subscriber number (N)" The subscriber number is the number unique to each individual telephone/mobile following the area/operator code. The Area/operator codes in Bangladesh are listed below, with a typical number format, where "X" denotes the Area/Operator code and "N" denotes the individual subscriber's telephone/mobile number. Area and operator codes Mobile Network Operators Typical format for a mobile phone number is 01XXX NNNNNN, e.g. 01054 694200 when dialed inside Bangladesh, and +880 1XXX NNNNNN when dialed internationally. 13 and 17 - Grameenphone 14 and 19 - Banglalink 15 - TeleTalk 1 ...

Interstate Highway System
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico. The U.S. federal government first funded roadways through the Federal Aid Road Act of 1916, and began an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921. In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were still state-funded and maintained, however, and there was little in the way of national standards for road design. U.S. Highways could be anything from a two-lane country road to a major multi-lane freeway. After Dwight D. Eisenhower became president in 1953, his administration ...

Dodge Custom 880
The Dodge Custom 880 is an automobile that was marketed by Dodge from 1962 through the end of the 1965 model year. It was to fill Dodge's product offer in the mid-price full-size market segment, as well as to help fill the void in Chrysler's lineup left by the discontinuation of DeSoto in 1961. Origins The Custom 880 was developed to fill consumer demand for a full-size Dodge passenger car during the 1962 model year. Chrysler's president overheard and misunderstood Chevrolet chief Ed Cole to have said Chevrolet's largest cars would be downsized for 1962. Chrysler designers were forced to take the planned 1962 Dodge full-size line and shorten the design to fit a more compact wheelbase in a last-minute effort to compete with what was supposed to be a smaller new Chevrolet. GM was developing a new mid-sized automobile that would become the 1964 Chevelle. But to Chrysler's shock and dismay, Chevrolet's 1962 full-size lineup emerged slightly ''larger'' than the 1961 models, with th ...
