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).

NGC 52
NGC 52 (PGC 978) is an edge-on spiral galaxy in the constellation Pegasus. It was discovered on September 18, 1784 by William Herschel. He described it as "very faint, small, extended." Physical Characteristics The galaxy is approximately 150,000 light years across. This makes it, in comparison, about 1.5 times as large as the Milky Way. The galaxy also has a satellite elliptical galaxy called PGC (Principal Galaxies Catalogue) 1563523.

Comic
a Media (communication), medium used to express ideas with images, often combined with text or other visual information. It typically the form of a sequence of Panel (comics), panels of images. Textual devices such as speech balloons, Glossary of comics terminology#Caption, captions, and onomatopoeia can indicate dialogue, narration, sound effects, or other information. There is no consensus amongst theorists and historians on a definition of comics; some emphasize the combination of images and text, some sequentiality or other image relations, and others historical aspects such as mass reproduction or the use of recurring characters. Cartoonist, Cartooning and other forms of illustration are the most common image-making means in comics; ''Photo comics, fumetti'' is a form that uses photographic images. Common forms include comic strips, Political cartoon, editorial and gag cartoons, and comic books. Since the late 20th century, bound volumes such as graphic novels, Bande d ...

Code For International Direct Dial
Country calling codes or country dial-in codes are telephone number prefixes for reaching telephone subscribers in the networks of the member countries or regions of the International Telecommunication Union (ITU). The codes are defined by the ITU-T in standards E.123 and E.164. The prefixes enable international direct dialing (IDD) and are also referred to as ''international subscriber dialing'' (ISD) codes. Country codes are a component of the international telephone numbering plan and are necessary only when dialing a telephone number to establish a call to another country. Country codes are dialed before the national telephone number. By convention, international telephone numbers are represented by prefixing the country code with a plus sign (+), which also indicates to the subscriber that the local international call prefix must first be dialed. For example, the international call prefix in all countries of the North American Numbering Plan is 011, while it is 00 in most ...
