Yesterday evening, Saturday, during the opening celebrations of the Mediterranean Games, pictures of the mathematician Leonardo Fibonacci appeared, which aroused the curiosity of the party’s followers.
Leonardo Fibonacci is a famous Italian mathematician whose real name is Leonardo Guglielmo Bonacci.
His father was a customs officer for the merchants of Pisa in the wilaya of Bejaia. Leonardo was educated mainly in the city of Bejaia, which was full of scholars in the field of mathematics such as Abu Mediene (or Sidi Boumediene), Ibn Hamad, Abd al-Haq al-Ishbili and Abu Hamid al-Saghir.
His father, Guillelmo Bonacci, was the supervisor of the Pisa markets in Algeria, Tunisia and Morocco.
Fibonacci, in the year 1200, transferred the Arabic numerals used today and algebraic signs to Europe and he issued a book entitled “Liber Apache”, which specializes in arithmetic and accounting.
In this book, Fibonacci was influenced by his life in the Arab countries, and this is evidenced by the fact that Fibonacci edited part of it from right to left. By publishing this book, Fibonacci introduced the Europeans to the Arabic arithmetic and writing systems. This system was far superior to the Roman system adopted at the time in Europe, and Fibonacci was aware of this.
