Numbers in Spanish

In Spain, for many centuries the Roman numeration system dominated. In the 8th century, Leonardo de Pisa, who had traveled through the

Middle East, introduced the Indo-Arabic system to Europe. In Spain, this numeration system appeared in manuscripts as early as 976 AD. Towards the year 1500, the system was already in place and used clearly in mathematical texts.

With the expanding European empires, the number system spread throughout the West, substituting local number systems such as those found in Latin America. One example of this was the very precise Mayan numerical system.

The Indo-Arabic numerical system is still used today and is the base of significant scientific development and universal mathematics.

One curiosity is the small difference between the Spanish numerical systems and the Anglo-Saxon one. In Spain a billón is one million millions, whereas in the Anglo-Saxon system, a billion is one thousand millions.

Spain: Un billón: 1.000.000.000.000
Anglo-Saxons: One billion: 1,000,000,000
Also opposite to the Anglo-Saxon system is the fact that in Spain the “.” symbol is used to separate thousands and “,” to indicate decimals.
3.537,52 € is equal to three thousand five hundred thirty-seven euros and fifty-two cents.
