We owe a lot to al-Khwarizmi, who probably does not have the celebrity he deserves in Europe. We owe him nothing less than our decimal system of numeration, and two fundamental words in the vocabulary of mathematics, that of Algorithm and that of Algebra. In this last field he achieves a notable progress, by his systematic treatment of the equations of degree two.

He represents here the numerous and valiant cohort of middle-eastern mathematicians, among whom we can mention Thâbit ibn Qurra (died in 901), Ibn al-Haytham, known as Alhazen (965-1039), al Karaji, who lived around the year 1000, Omar al-Khayyam (1048-1122), al-Tüsi (around 1170), al-Samaw'al (died in 1174), and many others ... It turns out that al-Khwarizmi is chronologically the first of them. He was a member of the "House of Wisdom" in Baghdad (a kind of research center, one can think of the "Museum" of Alexandria, which included Euclid and Eratosthenes).

As the founder of Arabic mathematics, he was also the introducer in his cultural area of ​​much of India's knowledge of mathematics. He wrote a treatise, which was not found (but which is known through his translations in Latin), in which he exposed the Indian decimal system, the methods of calculation in this system (addition , subtraction, multiplication ...), but also fractions, some calculations in sexagesimal system, square roots ...

If he gave the Arabs the Indian knowledge, al-Khwarizmi also offered them to the West, since it was thanks to the translation of his books in Latin that the Europeans were able to know and adopt the Indian decimal system, largely perfected in the meantime. by the Arabs. These translations appeared in Europe only in the twelfth century, under the significant titles of Dixit Algorizmi ("Al-Khwarizmi said that ..."), or (for the same book) "From Numero Indorum (The Indian Number ), or Liber Alchorismi (the book of Al-Khwarizmi) .This new and magnificent system of calculation was therefore designated by the Europeans as "algorism", in homage to the author of these works. al-Khwarizmi was the messenger of the Indian decimal system, which is now an important element of universal culture, not only in his own civilization, but also to Europe, through the Latin translations of his works.

Al-Khwarizmi has another title of glory, it is to have written a treatise on the equations of the second degree. These had been known for millennia, for example by the Babylonians, and general methods of resolution had been given for certain types of them by Euclid. But it is al-Khwarimi who develops the first a general classification, thanks to a global vision of the problem. It does not use any literal notation, and all its resolutions are in "common" language. The unknown is referred to as "the root" or "the thing". Resolutions are made, not by means of calculations, but by means of geometric constructions, in the Euclidean style. The title of his work is Kitab al-jabr wa al-muqabala, which can be translated as "the book of addition and balance". The work was translated into Latin in the twelfth century, under the title Algebra (Algebra in Latin), because the translator kept the Arabic word (the same phenomenon occurs nowadays for English words like "bug", or " plug-in ", that translators do not have the energy to translate into French). Here is the origin of one of the most important words of mathematics.

But besides the word, Al-Khwarizmi introduced in Arab countries as in the West the interest for the discipline itself, awakened also by the works of Euclid or Diophantus. The Arab successors made remarkable progress in algebra. It remained only in the Renaissance to solve in a general way the equation of the third degree before that of degree 5 (impossible resolution, as Evariste Galois demonstrated).
