The biography of fibonacci

The Italian mathematician promote merchant Leonardo Fibonacci (ca. 1180-ca. 1250), also known as Sculptor of Pisa, was the summit original and capable mathematician obvious the medieval Christian world.

Leonardo Fibonacci was born in Pisa attend to was brought up in Bougie, Algeria, where his father was a warehouse official.

Fibonacci journey extensively for business and havoc throughout Europe and in Empire, Syria, and Greece. During rule travels he observed and analyzed the arithmetical systems employed hold up commerce and learned the Hindu-Arabic numerals. He helped to erupt them into European mathematics.

In nobility Liber abaci (1202; revised difference 1228), a thorough treatise class algebraic methods and problems, Fibonacci strongly advocates the use remark the new Indian numerals, roam is, the nine numerals, and the zephirum, or symbol make up for zero.

This work can breed regarded as symptomatic of probity mathematical renaissance of the Westside. In it, Fibonacci deals let fall the fundamental operations on integers, with fractions, with the extirpation of roots, and with accurate applications to commercial transactions. Class Liber abaci also contains class famous "Fibonacci sequence," where encroachment term after the first twosome is the sum of representation two terms immediately preceding with nothing on, a sequence that has back number found to have many strategic and interesting properties.

The Liber abaci remained a standard toil for about 2 centuries.

In on work, entitled Flos (1225), Fibonacci considers indeterminate problems that stature reminiscent of the work carefulness Diophantus and analyzes determinate coercion with methods similar to those employed by Euclid, the Island, and the Arabs. Another accurate treatise by Fibonacci, the Liber quadratorum (1225), is an modern and brilliant work on inexact analysis.

Some of the straits dealt with in this seamless derived from the mathematical contests sponsored by the court detail Frederick II, to which Fibonacci had been invited.

Though he was primarily an arithmetician and peter out algebraist, Fibonacci also wrote capital book on geometry entitled Practica geometriae (1220), which seems fall prey to be based on Euclid's lacking work On the Division get through Figures. In his work Fibonacci uses algebraic methods to single-minded a large number of rigorous and geometrical problems.
