-
He was born on this time.
-
He travels to Bugia, Algeria and under his fathers commands he goes to an accounting school to learn Arab-Hindu mathematics under and Arab master. Later on, he also visits Egypt, Syria, Greece, Sicily, and Provence to collect data on their mathematical systems.
-
This is the Holy roman emperor of Rome who associated with Fibonacci. The emperor asked him for help to solve problems in Rome. This emperor was crowned when he was only 3 years old.
-
Now that he is done traveling, he has collected a lot of information which he then uses to write books on Hindu-Arab mathematics.
-
He publishes one of his best works. Introduction to Hindu-Arab mathematics and what we best know him by, "The Fibonacci Sequence".
-
While using the Fibonacci number, Fibonacci realizes that the fraction that repeats is a ratio that equals 1.618033988749… when divided.
-
A fleet of 200 ships fleet sail from the lagoons of Venice to reconquer Jerusalem which was conquered by the Islamic armies in the 7th century. This fleet was lead by Doge Enrico Dandolo (80 years old)
-
In this Book Fibonacci wrote about how to compute with Pisan (Italian) units of measure, find square and cube roots, determine dimensions of both rectilinear (A rectilinear figure is a figure all of whose edges meet at right angles) and curved surfaces and solids, work with tables for indirect measurement.
-
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.
-
Fibonacci was summoned by Frederick II (Holy Roman Emperor) in order to compete in mathematics.
-
Rome (king at that time was Frederick the 2nd) recognized him with a salary because, of the work and teaching he had done to improve the mathematics of that time.
-
He dies in 1250 in Italy.
-
He died in year 1250, which is the same year in which Fibonacci died
