Leonardo Fibonacci was born in Pisa, Italy. His actual name is Leonardo Pisano Bigollo. Scholars don't have an exact understanding of what "Bigollo" means but they think it may mean something along the lines of "good-for-nothing."
Study in North America
1190 - 1200
Leonardo Travels to North Africa to study and get a higher education. While there he learns the Arabic number system (1,2,3,10,100...).
Returns to Italy
After studying for many years in Northern Africa, Leonardo returned to Italy and wrote many of the important texts that are well known today and his best works. When he wrote the texts he introduced the new Arabic system to the European world.
The Golden Ratio
While using the Fibonacci number, Fibonacci realizes that the fraction that repeats is a ratio that equals 1.618033988749… when divided.
Writes Liber Abbaci
Leonardo writes Liber abbaci. The book is where the Fibonacci sequence was first introduced. The sequence was brought up when Fibonacci was thinking about rabbit populations. (1, 1, 3, 5, 8, 13...)
Writes Practica Geomatriae
Leonardo writes another book on geometry called Practica geometriae. The book is about how to solve geometric problems and apply them. Some examples are using similar triangle to find the height of tall buildings
He writes the book Flor.
Writes Liber Quadratorum
Leonardo writes a book Liber quadratorum on quadratic equations and how they could be used and solved. He proved many quadratic equation and other quadratic theories in this book. This is not is well known work however, to most scholars it is considered his best work.
Mathematical Competition in Pisa
Fibonacci was called by Frederick in order to compete in mathematics.
Rome gives Leonardo a salary in recognition of the work he had done for the world and teaching he had done for the people in Italy, and around the world.
