Latin name is Algori *** us. Spine submodule Famous mathematician, astronomer and geographer. Founder of algebra and arithmetic, known as "the father of algebra". At present, there is little information about Hua Lazimi's life, and even his birthplace has not been determined. Judging from his name, he may have come from Khorasan region, which was located in the eastern part of the Persian Empire at that time and is now Khorasan State of Uzbekistan. Biruni, a Persian scholar from Hualamozi, called the Hualamozi people "a branch of the Persian nation", that is, the Tajik people who live in Central Asia. Born in Khorezmo (now Shiva City, Khorezmo Prefecture, Uzbekistan). It is said that he has been to Afghanistan and India, and then settled in Baghdad for a long time. He once served in the court of Ma Meng, caliph of Abbasid Dynasty, presided over the work of "Wisdom Palace" in Karbach, and was responsible for collecting, sorting out and translating a large number of lost scientific, technical and mathematical works in ancient Greece and the East. He made contributions to astronomical calendars and geographical maps. His works had a positive impact on the birth of modern European science through later Latin translation. The manuscript of this book was published in the library of Cambridge University, England, until 1857. After Al-Khwarizmi left his hometown, he went to Baghdad, the academic center at that time, and worked at Samaxia Observatory, which belonged to the Hall of Wisdom (Jixian Hall) founded by Khalifa Ma Meng in Abbasi Dynasty (reign 8 13 ~ 833). He engaged in mathematical research and astronomical observation for a long time until his death in about 850. He absorbed and synthesized the achievements of mathematical works in ancient Babylon, Greece and India, and pushed the development of mathematics to a depth and breadth. His book Arithmetic systematically describes decimal notation and decimal operation, which has played a great role in the popularization of decimal notation in the world. In 830 AD, Al-Khwarizmi wrote a book about algebra called Hisab al-jabr wa'l-muqabalah. Historians have always had different opinions on the proper translation of the title of this book. Al-jabr originally meant to restore balance, which refers to an algebraic operation-after the term transfer is completed, the two ends of the equation restore balance (al-jabr also refers to the osteopath restoring broken bones). Wa'l-muqabalah means some kind of face-to-face fact, which refers to the algebraic operation of set terms here. Therefore, the title of the book can be translated into "The Science of Verbs and Determinants", but it is usually translated into "Calculation of Integrals and Equations". This book was translated into Owen, and after the title was gradually simplified, it was directly translated into algebra, from which the word algebra came. This book expounds the basic method of understanding the linear and quadratic equations and the calculation formula of the quadratic root (i.e. x2+ 10x=39), clearly puts forward a series of concepts such as algebra, known number, unknown number, root, shift term, set term, irrational number, etc., and contains more than 800 examples, providing algebraic calculation methods, and developing algebra into a discipline comparable to geometry. In addition, Indian numerals (1~ 9,0) were also introduced to the west through his works, and Europeans called them Arabic numerals. His Kitab al-Jabr wa-l-Muqabala is the first systematic work to solve the linear equation and quadratic equation of one variable, so it is called the creator of algebra [3], just like Diophantine. /kloc-in the 0/2nd century, Huala Mizi's works on Indian numerals were translated into Latin, so the decimal system was introduced to the western world [4]. In addition, he revised Ptolemy's geography and wrote books on astronomy and astrology. His contribution also has an influence on language. The word "algebra" comes from Arabic Latin transliteration "Al-Jabr" [5], and "Al-Jabr" is one of the two solutions of quadratic equation with one variable. Algorithm (Algorithmi * * *) comes from "Algorithmi", which is the Latin translation of al-Khwārizm. Spanish "guari *** o" and Portuguese "Algori *** * o" also come from this name, and both of them are interpreted as numbers.
At present, there is little information about Huala Mizi's life, and even his birthplace has not been determined. According to his name, he may come from Khorasan region, located in the eastern part of the Persian Empire at that time, which is now Khorasan Prefecture in Uzbekistan.

The meaning of the name of the statue of Ayatollah Ali (Ayatollah Ali, Uzbekistan) His full name is Abu Abdul Lo Muhammad ibn Musso Al-solarz Mi, which means "Muhammad, the father of Jia Faer, the son of Musa, from Ayatollah Ali". Arabic Al-khwarizmi originally meant from (al-) Xorazmiy. The character achievement Alvaramizi introduced Indian numerals and developed arithmetic, and then it was introduced to Europe through Fibonacci, gradually replacing the original tablet computing and Roman counting system in Europe. Europeans latinize the word Al-khwarizmi and call it guri *** o or algorithm. Guri *** o means decimal number, and the arithmetic using Indian Arabic numerals for routine calculation is called algorithm. Later, arithmetic was expressed in other words (such as arithmetic), and algorithm became the jargon of computer science-the "algorithm" on which computers depended. Alvara Mizi showed the basic methods of addition, subtraction, multiplication and division of numbers, and even showed how to find the square root and π. These methods are accurate, clear, legal, efficient, correct and simple. They are called "arithmetic rules". After many centuries, the decimal system was finally adopted in Europe, and this new term was also used to commemorate this philosopher. Since then, decimal system and its numerical algorithm have played a very important role in western civilization. It promotes the development of science and technology; Accelerated the development of industry and commerce. After a long time, with the appearance of computer, it clearly expressed the bits, words and arithmetic units in the bit value system. Scientists constantly develop complex algorithms to solve various problems, invent novel application software, and finally change the world. Algebra was translated into Latin in the12nd century and became a textbook for European universities until the17th century. Alhuala Mizi also drew lessons from the achievements of astronomical calendars in India, Persia and ancient Greece, and compiled the earliest astronomical calendar in Arabia, called Al-Khwarizmi Calendar, based on new observation data, which was popular in the Islamic world at that time. After this astronomical watch was used for 100 years, the Toledo catalog compiled by Spanish astronomer Maslei May was revised. 1 126 was translated into Latin by Edera, an Englishman, and became the blueprint of various astronomical calendars in the East and West. Based on Ptolemy's geography and on-the-spot investigation and calculation, he compiled the book The Shape of the Earth with maps, recorded 537 place names and their latitudes and longitudes, divided the topography and climatic zones of various places, expounded the original idea of eccentric shape of the earth, and laid the foundation for the development of Arabic geography. Western historians call him "one of the greatest Muslim scientists in the Islamic world". The main work, Al Khorezm, has two mathematical works handed down from generation to generation: one is only translated in Latin, and its title is Arithmetic of Al Khorezm. This book introduces Indian decimal notation and arithmetic knowledge based on it. The word "algorithm" in modern mathematics comes from this book, which is the name of Hua. Another book, Menzerbala and Almukabara, is a commemorative stamp issued by Uzbekistan Post Office, which means to reduce and cancel, suggesting that the two ends of the equation move items and merge similar items. This book is divided into three parts. The first part is about the solution of quadratic equation, in which the general solution of quadratic equation is given for the first time, and the corresponding geometric proof is given to ensure the correctness of the solution. This part was translated into Latin in the12nd century, and there are two different versions, which have been popular in Europe in the16th century. The title of this book was later translated into Algebra, which was translated into Chinese. The other two parts of the book are actual measurement and heritage calculation. Because of the importance of the first part of this book, some people praised Al-Khorezm as the originator of algebra. Huala Mizi's contributions to mathematics, geography, astronomy and cartography laid the foundation for the innovation of algebra and trigonometry. He gave birth to algebra by solving the linear equation and quadratic equation with one yuan, and the word algebra originated from his book Algebra.
About the use of Indian numerals, written in 825, is particularly important for the spread of the Indo-Arabic numeral system in the Middle East and Europe. It was translated into Latin "Algoritmi de numero Indorum", and the Latin transliteration of Hua Lamizi is the origin of the word "algorithm" [14].
Some of his works are based on Persian and Babylonian astronomy, Indian numerals and Greek mathematics.
Huala Mizi compiled and revised Ptolemy's information about Africa and the Middle East. Another important book of his, Kitab surat al-ard, lists the geographical coordinates according to Ptolemy's Geographic Guide, and adds the contents of Mediterranean, Asia and Africa [15].
He also wrote documents recording mechanical equipment, such as astrolabes and sundials.
He participated in the project of measuring the circumference of the earth and instructed 70 geographers to draw a map of the world for the caliph Ma Meng [16].
/kloc-in the 0/2nd century, the Latin translation of Huala Mizi's works was introduced into Europe, which had a far-reaching impact on the development of European mathematics. He introduced Arabic numerals to the west on the basis of Indian decimal value system. Statue of Hua Razimi (urgench, Uzbekistan) He was also the first author to write history books in Arabic, and some of his "history books" remained.
