Abu Ja’far Muhammad bin Musa al-Khawarizmi or a well-known al-Khawarizmi was a Muslim intellectual who contributed greatly to his work in mathematics. He was the first Muslim and distinguished in mathematics or mathematics in the golden age of Islamic science. He was born in Khawarizmi, Uzbekistan, in 780 AD.

His intelligence and intelligence enabled him to lead Al-Khawarizmi into the circle of Dar al-Hukama, a research and development institute of knowledge founded by Ma’mun ar-Rashid, a well-known Abbasid Caliphate.

Without connecting with the scholarly works of Muslim mathematicians such as Al-Khawarizmi, the figures in the Copernicus era are hardly regarded as intellectuals in mathematics. For this reason, they copy practical examples, such as calculating the height of a mountain, the depth of a valley, and the distance between two objects or uneven surfaces of Al-Khawarizmi.

Meanwhile, the writings on algebra began by Diophantus of Greece in 250 BC, have been corrected and reiterated, and compiled by Al-Khawarizmi. In fact, Al-Khawarizmi also provided some formulas, including triangular formulas and how to compile logarithmic lists.

In the West, especially in Europe, Al-Khawarizmi is known as Algorism or Algorism. He has developed other mathematical theories, including algebra, which Western scholars call arithmetic using Arabic numerals. The term “algebra” is derived from the title of his essay, Al-Jabr wa al-Muqabilah.

In this book, he summarizes and explains the trigonometric tables we usually study in detail. It also explores basic calculus theories in a simple way. In the end,

Al-Khwarizmi is a pillar in the history of algebra that is currently developing into mathematics. In fact, he has made algebra into an exact science. Therefore, he is called the Father of Algebra.

His work also contains descriptions of addition, subtraction, multiplication, and division operations. Later, this system of mathematical operations expanded to Europe through Spain and became a reference to several European mathematicians, including Fibonacci and Berbert d’Aurignac.

Al-Khwarizmi also developed hexadecimal fractionation operations for astronomical calculation purposes.

His work, also contains geometric meanings. In this case, he contributes the triangle theorem to calculate the area of triangles, angles, and circles, and triangles.

Meanwhile, until the 13th century, people in Western Europe still wore Roman numerals. This makes the operation of science difficult to do and hinders the development of the theory of science for sure.

Thanks to the services of Italian scientist Leonardo Febonacci, European scientists began using Arabic numerals as used by Al-Khawarizmi. At that time, the French people began to use these numbers in their counting practices. With the introduction of this number, a few words from Arabic have entered European language.

The word chiffre in French, ziffer in German, chiper in English, zero in French and English, comes from shifr glass in Arabic meaning zero.

The word is used to describe a vacancy at a certain number of levels, such as units, tens, hundreds, and so on. The number zero is rounded and in it is empty.

Thus, Al-Khawarizmi’s two most important mathematical works are Hisab al-Jabr wa al-muqabla and Al-Jama’wa at-Tafriq bi Hisab al-Hind. Both works deal with linear and quadratic equations, integration calculations, and equations with 800 different examples, as well as negative signs previously unknown to the Arabs. In fact, in Al-Jama’wa at-Tafriq he also explains the intricacies of numbers, including zero in everyday life. The work has also been translated into Latin.

In addition, Al-Khawarizmi’s contribution to the field of angular sciences is also outstanding. The tables of angular scaling related to the function of the sine and the tangent lines of its findings have helped Europeans to understand the science in greater depth.

Until the mid-16th century, European universities still used Al-Khawarizmi’s textbooks as references and textbooks. His book entitled Trattati d’Arithmetica has been translated into Latin.

In 1857 the book was published in Rome. The book talks about some of the statistics, the origins of numbers, and the history of numbers used today.

After translating into Latin, his works are also translated into other languages, including Chinese.

Dalam salah satu buku matematikanya, Al-Khawarizmi juga menuliskan teori seni musik. Pengaruh buku ini sampai ke Eropa dan dianggap sebagai perkenalan musik Arab ke dunia Latin. Tokoh yang meninggal pada tahun 846M di Bagdad dan meninggalkan karya-karya besar ini dianggap sebagai ilmuwan terkemuka dalam bidang matematika.

In one of his mathematical books, Al-Khawarizmi also wrote the art theory of music. The influence of this book reaches Europe and is considered an introduction to Arabic music in the Latin world. People who died in 846 AD in Baghdad and left these great works are considered as leading scientists in the field of mathematics.
