Fibonacci was known for many things. He was best known for the Fibonacci Numbers, which I will discuss later on.
Born in Pisa, Italy, Fibonacci studied mathematics in Bugia, Africa. Following, he travelled widely and recognized the enormous advantages of the mathematical systems used in different countries, which he wrote about in his famous book Liber abaci. You might think that at a time when Europe was little interested in scholarship, Fibonacci would have been easily ignored. This, however, is not so and interest in his work contributed strongly to his importance. He was a very sophisticated mathematician and his achievements were clearly recognized, although it was the practical applications rather than the abstract theorems that made him famous to his contemporaries.
The famous Fibonacci numbers is a number sequence that Leonardo while solving a problem about rabbits. Originally, it was a problem that he was investigating to see how fast rabbits would breed in ideal circumstances. The population of rabbits was recorded each month and was as follows: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…… The numbers are significant because each number > 1 is the sum of the two preceding numbers. Fibonacci was able to come up with the equation:
0 if n = 0;
F(n) := 1 if n = 1;
F(n – 1) + F(n – 2) if n > 1.

The Fibonacci numbers are still used today for solving mathematical problems.
