43 Muhammad ibn Ahmad al-Khwarizmi, in 976, stated that if no number appears in the place of tens in a calculation, a little circle should be used "to keep the rows". This circle was called ṣifr. 45 Transmission to europe The hinduArabic numeral system (base 10) reached Europe in the 11th century, via the Iberian Peninsula through Spanish Muslims, the moors, together with knowledge of astronomy and instruments like the astrolabe, first imported by gerbert of Aurillac. For this reason, the numerals came to be known in Europe as "Arabic numerals". The Italian mathematician Fibonacci or leonardo of Pisa was instrumental in bringing the system into european mathematics in 1202, stating: After my father's appointment by his homeland as state official in the customs house of Bugia for the pisan merchants who thronged to it,. There, following my introduction, as a consequence of marvelous instruction in the art, to the nine digits of the hindus, the knowledge of the art very much appealed to me before all others, and for it I realized that all its aspects were studied. I pursued my study in depth and learned the give-and-take of disputation. But all this even, and the algorism, as well as the art of Pythagoras, i considered as almost a mistake in respect to the method of the hindus (Modus Indorum). Therefore, embracing more stringently that method of the hindus, and taking stricter pains in its study, while adding certain spieropbouw things from my own understanding and inserting also certain things from the niceties of Euclid's geometric art. I have striven to compose this book in its entirety as understandably as I could, dividing it into fifteen chapters. Almost everything which I have introduced I have displayed with exact proof, in order that those further seeking this knowledge, with its pre-eminent method, might be instructed, and further, in order that the latin people might not be discovered to be without it, as they. If I have perchance omitted anything more or less proper or necessary, i beg indulgence, since there is no one who is blameless and utterly provident in all things. The nine Indian figures are. With these nine figures, and with the sign.

The earliest known material use of zero as a decimal figure. There are numerous copper plate inscriptions, with the sportschool same small o in them, some of them possibly dated to the 6th century, but their date or authenticity may be open to doubt. 13 A stone tablet found in the ruins of a temple near Sambor on the mekong, kratié province, cambodia, includes the inscription of "605" in Khmer numerals (a set of numeral glyphs of the hindu numerals family). The number is the year of the inscription in the saka era, corresponding to a date of AD 683. 38 The first known use of special glyphs for the decimal digits that includes the indubitable appearance of a symbol for the digit zero, a small circle, appears on a stone inscription found at the Chaturbhuja temple at Gwalior in India, dated 876. 39 40 Zero is also used as a placeholder in the bakhshali manuscript, portions of which date from ad 224383. 41 Middle Ages Transmission to Islamic culture see also: History of the hinduArabic numeral system The Arabic -language inheritance of science was largely Greek, 42 followed by hindu influences. 43 In 773, at Al-Mansur 's behest, translations were made of many ancient treatises including Greek, roman, Indian, and others. In ad 813, astronomical tables were prepared by a persian mathematician, muammad ibn Mūsā al-Khwārizmī, using Hindu numerals; 43 and about 825, he published a book synthesizing Greek and Hindu knowledge and also contained his own contribution to mathematics including an explanation of the use. 44 This book was later translated into latin in the 12th century under the title Algoritmi de numero Indorum. This title means "al-Khwarizmi on the numerals of the Indians". The word "Algoritmi" was the translator's Latinization of Al-Khwarizmi's name, and the word "Algorithm" or "Algorism" started meaning any arithmetic based on decimals.

three samples from the manuscript were shown by radiocarbon dating to come from three different centuries: from 224-383 ad, 680-779 ad, and 885-993 ad, making it the world's oldest recorded use of the zero symbol. It is not known how the birch bark fragments from different centuries that form the manuscript came to be packaged together. The origin of the modern decimal-based place value notation can be traced to the Aryabhatiya (c. . 500 which states sthānāt sthāna daśaguṇa syāt "from place to place each is ten times the preceding." The concept of zero as a digit in the decimal place value notation was developed in India, presumably as early as during the gupta period (c. 5th century with the oldest unambiguous evidence dating to the 7th century. 36 The rules governing the use of zero appeared for the first time in Brahmagupta 's Brahmasputha siddhanta (7th century). This work considers not only zero, but negative numbers, and the algebraic rules for the elementary operations of arithmetic with such numbers. In some instances, his rules differ from the modern standard, specifically the definition of the value of zero divided by zero as zero. 37 Epigraphy The number 605 in Khmer numerals, from the sambor inscription ( saka era 605 corresponds to ad 683).

According to a history of Mathematics, the rods "gave the decimal representation of a number, with an empty space denoting zero." 19 The counting rod system is considered a positional notation system. 20 In ad 690, empress Wǔ promulgated Zetian characters, one of which was ". The word is now used as a synonym for the number zero. Zero was not treated as a number at that time, but as a "vacant position". 21 Qín Jiǔsháo 's 1247 Mathematical Treatise in Nine sections is the oldest surviving Chinese mathematical text using a round symbol for zero. 22 Chinese authors had been familiar with the idea of negative numbers by the han Dynasty (2nd century ad as seen in The nine Chapters on the mathematical Art, 23 much earlier than the 15th century when they became well-established in Europe. 22 India pingala (c. 3rd/2nd century bc 24 a sanskrit prosody scholar, 25 used binary numbers in the form of short and long syllables (the latter equal in length to two short syllables a notation similar to morse code. 26 Pingala used the sanskrit word śūnya explicitly to refer to zero. 27 It was considered that the earliest text to use a decimal place-value system, including a zero, is the lokavibhāga, a jain koopakte text on cosmology surviving in a medieval Sanskrit translation of the Prakrit original, which is internally dated to ad 458 ( saka era 380). In this text, śūnya void, empty is also used to refer to zero.

Because it was used alone, not just as a placeholder, this Hellenistic zero was perhaps the earliest documented use of a numeral representing zero in the Old World. 17 However, the positions were usually limited to the fractional part of a number (called minutes, seconds, thirds, fourths, etc.)—they were not used for the integral part of a number, indicating a concept perhaps better expressed as "none rather than "zero" in the modern sense. In later byzantine manuscripts of Ptolemy's Almagest, the hellenistic zero had morphed into the Greek letter omicron (otherwise meaning 70). Another zero was used in tables alongside roman numerals by 525 (first known use by dionysius Exiguus but as a word, nulla meaning "nothing not as a symbol. 18 When division produced zero as a remainder, nihil, also meaning "nothing was used. These medieval zeros were used by all future medieval calculators of Easter. The initial "N" was used as a zero symbol in a table of Roman numerals by bede or his colleagues around 725. China This is a depiction of zero expressed in Chinese counting rods, based on the example provided by a history of Mathematics. An empty space is used to represent zero. 19 The sūnzĭ suànjīng, of unknown date but estimated to be dated from the 1st to 5th centuries ad, and Japanese records dated from the 18th century, describe how the. 4th century bc chinese counting rods system enables one to perform decimal calculations.

Quipu, a knotted cord device, used in the Inca Empire and its predecessor societies in the Andean region to record accounting and other digital data, is encoded in a base ten positional system. Zero is represented by the absence of a knot in the appropriate position. Classical antiquity The ancient Greeks had no symbol for zero (μηδέν and did not use a digit placeholder for. 16 They seemed unsure about the status of zero as a number. They asked themselves, "How can nothing be koopakte something? leading to philosophical and, by the medieval period, religious arguments about the nature and existence of zero and the vacuum. The paradoxes of Zeno of Elea depend in large part on the uncertain interpretation of zero. Example of the early Greek symbol for zero (lower right corner) from a 2nd-century papyrus by 130 ad, ptolemy, influenced by hipparchus and the babylonians, was using a symbol for zero (a small circle with a long overbar) in his work on mathematical astronomy called the. The way in which it is used can be seen in his table of chords in that book. Ptolemy's zero was used within a sexagesimal numeral system otherwise using alphabetic Greek numerals.13 The babylonian placeholder was not a true zero because it was not used alone. Nor was it used at the end of a number. Thus numbers like 2 and 120 (260 3 and 180 (360 4 and 240 (460 looked the same because the larger numbers lacked a final sexagesimal placeholder. Only context could differentiate them. Pre-columbian Americas The back of Epi-Olmec stela c from Tres Zapotes, the second oldest Long count date discovered. The numerals.18 translate to september, 32 BC (Julian). The glyphs surrounding the date are thought to be one of the few surviving examples of Epi-Olmec script. The mesoamerican Long count calendar developed in south-central Mexico and Central kopen America required the use of zero as a place-holder within its vigesimal (base-20) positional numeral system. Many different glyphs, including this partial quatrefoil — —were used as a zero symbol for these long count dates, the earliest of which (on Stela 2 at Chiapa de corzo, chiapas ) has a date of 36 BC. A since the eight earliest Long count dates appear outside the maya homeland, 14 it is generally believed that the use of zero in the Americas predated the maya and was possibly the invention of the Olmecs. 15 Many of the earliest Long count dates were found within the Olmec heartland, although the Olmec civilization ended by the 4th century bc, several centuries before the earliest known Long count dates. Although zero became an integral part of maya numerals, with a different, empty tortoise -like " shell shape " used for many depictions of the "zero" numeral, it is assumed fitness to have not influenced Old World numeral systems.

It is often called oh in the context of telephone numbers. Slang words for zero include zip, zilch, nada, and scratch. Duck egg and goose egg are also slang for zero. 11 History Ancient near East nfr heart with trachea beautiful, pleasant, spel good Ancient Egyptian numerals were base. They used hieroglyphs for the digits and were not positional. By 1770 bc, the Egyptians had a symbol for zero in accounting texts. The symbol nfr, meaning beautiful, was also used to indicate the base level in drawings of tombs and pyramids and distances were measured relative to the base line as being above or below this line. 12 by the middle of the 2nd millennium bc, the babylonian mathematics had a sophisticated sexagesimal positional numeral system. The lack of a positional value (or zero) was indicated by a space between sexagesimal numerals. By 300 bc, a punctuation symbol (two slanted wedges) was co-opted as a placeholder in the same babylonian system. In a tablet unearthed at Kish (dating from about 700 bc the scribe bêl-bân-aplu wrote his zeros with three hooks, rather than two slanted wedges.

5 Contents Etymology main articles: Names for the number 0 and Names for the number 0 in English The word zero came into the English language via french zéro from Italian zero, italian contraction of Venetian zevero sporten form of 'Italian zefiro via ṣafira or ṣifr. 6 In pre-Islamic time the word ṣifr (Arabic ) had the meaning "empty". 7 Sifr evolved to mean zero when it was used to translate śūnya (Sanskrit: ) from India. 7 The first known English use of zero was in 1598. 8 The Italian mathematician Fibonacci (c. 11701250 who grew up in North Africa and is credited with introducing the decimal system to europe, used the term recepten zephyrum. This became zefiro in Italian, and was then contracted to zero in Venetian. The Italian word zefiro was already in existence (meaning "west wind" from Latin and Greek zephyrus ) and may have influenced the spelling when transcribing Arabic ṣifr. 9 Modern usage There are different words used for the number or concept of zero depending on the context. For the simple notion of lacking, the words nothing and none are often used. Sometimes the words nought, naught and aught 10 are used. Several sports have specific words for zero, such as nil in association football (soccer love in tennis and a duck in cricket.
