Leonardo Fibonacci is famous for popularizing the Hindu-Arabic numeral system in Europe and for introducing the mathematical sequence now known as the Fibonacci sequence.[8] His most influential work, Liber Abaci (“Book of Calculation”), published in 1202, demonstrated the superiority of the decimal number system over Roman numerals and provided practical applications for merchants and mathematicians, including bookkeeping, currency conversion, and interest calculations.[4]
The Liber Abaci also introduced the famous rabbit population problem, which led to the creation of the Fibonacci sequence, a series in which each number is the sum of the two preceding ones. This sequence has found profound applications in mathematics, computer science, and modeling natural phenomena.[2]
Beyond the sequence, Fibonacci’s legacy includes significant advancements in number theory. In his later work, Liber Quadratorum (“Book of Square Numbers”), he investigated properties of squares, methods to identify Pythagorean triples, and innovative solutions for quadratic Diophantine equations.[1] He also helped introduce mathematical notation, such as the modern fraction bar and approaches to square root notation, making calculations easier for future generations.[3]
Fibonacci’s contributions helped shift European mathematics toward more abstract and practical methods, influencing not only his contemporaries but also laying foundational work for future mathematicians.[7]
