Context

Fibonacci was an Italian mathematician who lived during the 12th century. Throughout his extensive travels in the Mediterranean and North Africa, he encountered the Arabic numeral system. As a distinguished mathematician, he quickly recognized the superior qualities of position-based digits in simplifying arithmetic and mathematical operations. The inclusion of zero in these numerals represented a remarkable achievement for the mathematical knowledge of that era.

During his journeys, Fibonacci came across the Arabic numeral system, which proved significantly more efficient and versatile compared to the Roman numeral system. The Arabic numerals featured the presence of zero and a place-value system, greatly enhancing the ease of calculations and arithmetic operations.

The power of the decimal system derives from its position-based nature, which was a stark contrast to the Roman numeral system's limitations. It's worth noting that the Babylonians also utilized a position-based system with a base of 60.

The adoption of Arabic numerals in Europe was largely facilitated by Fibonacci's influential book, "Liber Abaci." This work is widely regarded as one of the most important mathematical contributions in history. In this book, Fibonacci compiled mathematical knowledge from India to the Middle East, showcasing the practicality and efficiency of the Arabic numeral system.
