Leonardo Pisano Blgollo
(1170 to 1250)
Fibonacci's contributions to mathematics are remarkable. Even in the world today, we still make daily use of his discovery. His most outstanding contribution would be the replacement of decimal number system. Yet, few people realized it. Fibonacci had actually replaced the old Roman numeral system with theHindu-Arabic numbering system, which consists of Hindu-Arabic(0-9) symbols. There were some disadvantages with the Roman numeral system: Firstly, it did not have 0's and lacked place value; Secondly, an abacus was usually required when using the system. However, Fibonacci saw the superiority of using Hindu-Arabic system and that is the reason why we have our numbering system today. He had included the explanation of our current numbering system in his book\Liber Abaci". The book was published in 1202 after his return to Italy. It was based on the arithmetic and algebra that Fibonacci had accumulated during his travels.
Fibonacci was born in Italy but was educated in North Africa where his father, Guilielmo, held a diplomatic post. 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. Bejaia is a Mediterranean port in northeastern Algeria. The town lies at the mouth of the Wadi Soummam near Mount Gouraya and Cape Carbon. 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. Fibonacci writes in his famous book Liber abaci (1202). Leonardo Pisano is better known by his nickname Fibonacci. He was born in Italy but was educated in North Africa where his father held a diplomatic post. Fibonacci was taught mathematics in Bugia and travelled widely with his father, recognising the enormous advantages of the mathematical systems used in the countries they visited. Fibonacci ended his travels around the year 1200...
