One might have thought that at a time when Europe was little interested in scholarship, Fibonacci would have been largely ignored. His book on commercial arithmetic Di minor guisa в“‰ ( Book of small ways ) is lost as is his commentary on Book X of Euclid's Elements which contained a numerical treatment of irrational numbers which Euclid had approached from a geometric point of view. However, we know that he wrote some other texts which, unfortunately, are lost. Given that relatively few hand-made copies would ever have been produced, we are fortunate to have access to his writing in these works. Of his books we still have copies of Liber abaci в“‰ ( Book of the abacus ) (1202), Practica geometriae в“‰ ( Practical geometry ) (1220), Flos в“‰ ( Flower ) (1225), and Liber quadratorum в“‰ ( Book of squares ). Fibonacci lived in the days before printing, so his books were hand written and the only way to have a copy of one of his books was to have another hand-written copy made. There he wrote a number of important texts which played an important role in reviving ancient mathematical skills and he made significant contributions of his own. There, when I had been introduced to the art of the Indians' nine symbols through remarkable teaching, knowledge of the art very soon pleased me above all else and I came to understand it, for whatever was studied by the art in Egypt, Syria, Greece, Sicily and Provence, in all its various forms.ДЇibonacci ended his travels around the year 1200 and at that time he returned to Pisa. When my father, who had been appointed by his country as public notary in the customs at Bugia acting for the Pisan merchants going there, was in charge, he summoned me to him while I was still a child, and having an eye to usefulness and future convenience, desired me to stay there and receive instruction in the school of accounting. Fibonacci writes in his famous book Liber abaci в“‰ ( Book of the abacus ) (1202):. Fibonacci was taught mathematics in Bugia and travelled widely with his father and recognised the enormous advantages of the mathematical systems used in the countries they visited. The town lies at the mouth of the Wadi Soummam near Mount Gouraya and Cape Carbon.

Bejaia is a Mediterranean port in northeastern Algeria.

His father's job was to represent the merchants of the Republic of Pisa who were trading in Bugia, later called Bougie and now called Bejaia. As stated in :-Дid his countrymen wish to express by this epithet their disdain for a man who concerned himself with questions of no practical value, or does the word in the Tuscan dialect mean a much-travelled man, which he was?ДЇibonacci was born in Italy but was educated in North Africa where his father, Guilielmo, held a diplomatic post. Fibonacci himself sometimes used the name Bigollo, which may mean good-for-nothing or a traveller. He was the son of Guilielmo and a member of the Bonacci family. Biography Leonardo Pisano is better known by his nickname Fibonacci.
