Fibonacci’s greatest accomplishment was the introduction of the Hindu-Arabic numbering system to Europe around the beginning of the 13th century. Prior to this point, Europeans primarily relied on Roman numerals. However, Fibonacci felt that Hindu-Arabic numerals were much easier to use when performing arithmetic, which led him to publish “Liber Abaci,” a book that outlined the new numbering system.
Fibonacci is also famous for something called “Fibonacci numbers,” which refers to a sequence, or pattern, of numbers. In a Fibonacci series, each number is equal to the sum of the two previous numbers. For example, 1 1 2 3 5 is a Fibonacci sequence, as one plus one equals two; two plus one equals three; and two plus three equals five. Fibonacci did not invent the sequence; he merely introduced it to the Western world. The pattern was known in India as early as the sixth century.
In the 1800s, the city of Pisa erected a statue of Fibonacci.Learn more in Numbers
