Fibonacci was born in Italy but was educated in North Africa, where his father held a diplomatic post. He travelled widely with his father, recognizing the enormous advantages of the mathematical systems used in the countries he visited. _Liber Abaci_, published in 1202 after his return to Italy, is based on bits of arithmetic and algebra that Fibonacci had accumulated during his travels. A problem in _Liber Abaci_ led to the introduction of the Fibonacci numbers and the Fibonacci sequence for which Fibonacci is best remembered today. The _Fibonacci Quarterly_ is a modern journal devoted to studying mathematics related to this sequence. Fibonacci's other books of major importance are _Practica Geometriae_, published in 1220, which contains a large collection of geometry and trigonometry. In _Liber Quadratorum_, published in 1225, he approximates a root of a cubic obtaining an answer which in decimal notation is correct to 9 places. _Mis Practica Geometriae_, published in 1220, gives a compilation of the geometry of the time and also introduces some trigonometry.
