Liber Abaci triggers widespread adoption of the Hindu numeral system by Europe
In the Liber Abaci (1202), Fibonacci introduced the so-called modus Indorum (method of the Indians), today known as the Hindu numeral system. The manuscript book advocated numeration with the digits 0–9 and place value.
The book showed the practical use and value of the new Hindu numeral system by applying the numerals to commercial bookkeeping, converting weights and measures, calculation of interest, money-changing, and other applications. The book was well-received throughout educated Europe and had a profound impact on European thought.
