1. Liber AbaciLiber Abaci (1202, also spelled as Liber Abbaci) is a historic book on arithmetic by Leonardo of Pisa, known later by his nickname Fibonacci. In this work, Fibonacci introduced to Europe the Hindu-Arabic numerals, a major element of our decimal system, which he had learned by studying with Arabs while living in North Africa with his father, Guglielmo Bonaccio, who wished for him to become a merchant. Liber Abaci was among the first Western books to describe Arabic numerals.
