The numeric system represented by Roman numerals originated in ancient Rome BC— AD and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages generally comprising the 14th and 15th centuries c. Numbers in this system are represented by combinations of letters from the Latin alphabet. Roman numerals, as used today, are based on seven symbols:. The use of Roman numerals continued long after the decline of the Roman Empire.
From the 14th century on, Roman numerals began to be replaced in most contexts by the more convenient Hindu-Arabic numerals; however, this process was gradual, and the use of Roman numerals persists in some minor applications to this day. Numbers are formed by combining symbols and adding the values, so II is two two ones and XIII is thirteen a ten and three ones.
Symbols are placed from left to right in order of value, starting with the largest. However, in a few specific cases, to avoid four characters being repeated in succession such as IIII or XXXX , subtractive notation is used: as in this table:. By the 11th century, Hindu—Arabic numerals had been introduced into Europe from al-Andalus, by way of Arab traders and arithmetic treatises. Roman numerals, however, proved very persistent, remaining in common use in the West well into the 14th and 15th centuries, even in accounting and other business records where the actual calculations would have been made using an abacus.
A few examples of their current use are:. Skip to main content. Module 1: Historical Counting Systems. If we compare these to the Gupta numerals above, we can try to see how that evolutionary process might have taken place, but our imagination would be just about all we would have to depend upon since we do not know exactly how the process unfolded. The Gupta numerals eventually evolved into another form of numerals called the Nagari numerals, and these continued to evolve until the 11 th century, at which time they looked like this: [viii].
Note that by this time, the symbol for 0 has appeared! The Mayans in the Americas had a symbol for zero long before this, however, as we shall see later in the chapter. These numerals were adopted by the Arabs, most likely in the eighth century during Islamic incursions into the northern part of India.
Finally, one more graphic[xiii] shows various forms of these numerals as they developed and eventually converged to the 15 th century in Europe. More important than the form of the number symbols is the development of the place value system. Although it is in slight dispute, the earliest known document in which the Indian system displays a positional system dates back to C. However, some evidence suggests that they may have actually developed a positional system as far back as the first century C.
The Indians were not the first to use a positional system. The Babylonians as we will see in Chapter 3 used a positional system with 60 as their base. However, there is not much evidence that the Babylonian system had much impact on later numeral systems, except with the Greeks. Also, the Chinese had a base system, probably derived from the use of a counting board[xiv]. Some believe that the positional system used in India was derived from the Chinese system.
Wherever it may have originated, it appears that around C. Interestingly, the earliest dated inscriptions using the system with a symbol for zero come from Cambodia. In , the th year of the Saka era is written with three digits and a dot in the middle. The th year uses three digits with a modern 0 in the middle.

Interestingly, he did this in words rather than with the system of notation used in algebra today, which developed during the Renaissance. By the tenth century, they had reached Spain, most of which was under Muslim rule at that time.
During the 11th and 12th centuries, Christian forces in the north of the Iberian peninsula began conquering the great cities of al-Andalus. Toledo fell in , and over the following decades European scholars came to the city in search of Arabic books, including texts by al-Khwarizmi, which they translated into Latin. These scholars may have already been acquainted with the forms of the numerals themselves, which were present on a certain type of abacus counting board thought to have been introduced by a tenth-century monk named Gerbert later Pope Sylvester II whose talent and passion for mathematics took him to Spain in search of knowledge.
Thus the Hindu-Arabic numerals and system of place-value were gradually introduced to Europe. It was a slow process, in part because of resistance from Christians who regarded the numerals as evil and dangerous — simply because they came from the Muslim world. The most important figure in the transmission of the Hindu-Arabic system to Europe was not Spanish but Italian, and learned the numerals not in Spain but in Africa: Leonardo of Pisa, known today as Fibonacci though that name was applied to him only from the 19th century.
As a teenager, Fibonacci travelled around the eastern Mediterranean with his father, thereby enjoying opportunities to compare several systems of calculation in use at that time.
He quickly recognised the enormous potential of the Hindu-Arabic system to transform learning in the west. In he wrote a book titled Liber abbaci Book of Calculation. In this book, the first original work in Latin on the subject, he explained the workings of each of the numerals and the method of writing numbers in order according to their value. It detailed how to work out transactions in different currencies, and how to use different systems of weights and measures — methods that became increasingly important as Europe grew in prosperity and the mercantile world expanded and developed.
Merchants needed to be able to carry out complex calculations and record their accounts effectively — something that was made possible by the Hindu-Arabic system of numerals as expounded by Fibonacci. The more complex aspects of his writings were taken up later and helped to bring about advances in theoretical mathematics.
In the 15th and 16th centuries, scholars began to use the numerals in their exploration of algebra, especially after when the Flemish mathematician Simon Stevin published an innovative pamphlet on decimal fractions.
