da Vinci of Pisa or Fibonacci and the Issue of Moneylenders NFaly Konate Texas A&M University rally Texas FIN 590 Dr. Mary Kelly Summer 2012 blue Italy in the early thirteen degree Celsius was a land subdivided into multiple feuding city-states. Among the many remnants of defunct Roman Empire was a numerical system (I, ii, iii, iv) singularly ill suited to complex numerical computing, let alone the needs of moneymaking(a) system. nowhere was this more of a problem than in Pisa, where merchants alike had to contend with seven unlike forms of coinage in circulation.By comparison, economical animateness in the Eastern world was removed more advanced, just as it had been in the time of Charlemagne. To discover modern finance, europium needed to import it. In this, a young mathematician called Leonardo of Pisa, or Fibonacci play a crucial role. Leonardo Fibonacci also known as Leonardo Pisano, Leonardo of Pisa,was the greatest atomic number 63an mathematician of the middle ages . He was born in Pisa in Italy circa 1170 and died past after 1240.Leonardos father, Gugliemo, was a springer official and engaged in commerce representing Pisa at Bougie on the north sloping trough of Africa. Young Leonardo consequently legitimate a Moorish education as well as the traditional European education and was introduced to Hindu-Arabic song. Later on, he traveled about the Mediterranean visiting Egypt, Syria, Greece, Sicily and Provence, meet with scholars and becoming acquainted with the various arithmetical systems used by the merchants.In his make, the Liber abaci, which fills 459 printed pages, he explained the nearly perfect methods of calculating with whole numbers and with fractions, practice, extraction of the square and cube roots, proportion, mountain chain rule, finding of proportional parts, averages, progressions, even obscure interest, just as in the completest mercantile arithmetic of later days. They teach moreover the solution of problems lea ding to equations of the first and aid degree, to determinate and indeterminate equations, not by single and double position only, only if by real algebra, proved by means of geometric onstructions, and including the use of garner as symbols for known numbers, the unknown sum of money being called res and its square census. The book is also largely responsible for introducing Arabic numerals to Europe. Leonardo of Pisa is also considered a expose Player in the Finance because of his interpolation of Hindu-Arabic numerals. Finally, he not only gave Europe the decimal system, which makes all kinds of calculation outlying(prenominal) easier than with Roman numerals, he also showed how it could be applied to commercial bookkeeping, to currency conversions and crucially, to the calculation of interest.References 1) Ferguson, N (2008).
