|List of numeral systems|
Most of the positional base 10 numeral systems in the world have originated from the Indian subcontinent, where the concept of positional numeration was first developed. The Indian numeral system is commonly referred to in the West as the Hindu-Arabic numeral system or just Arabic numerals, since it reached Europe through the Arabs.

Since Sanskrit is an Indo-European language, it is obvious (as also seen from the table) that the words for numerals closely resemble those of Greek and Latin. The word "Shunya" for zero was translated into Arabic as "صفر" "sifr", meaning 'nothing' which became the term "zero" in many European languages from Medieval Latin, zephirum (Arabic: sifr).

In Sinhala language (Sinhala alphabet) Sinhalese numerals were used at least until the 19th century, but they're now obsolete in favor of Arabic numerals. Sinhalese numerals are not encoded in Unicode as of version 6.2.
Other modern Indian languages 
The five Indian languages (Hindi, Marathi, Konkani, Nepali and Sanskrit itself) that have adapted the Devanagari script to their use also naturally employ the numeral symbols above; of course, the names for the numbers vary by language. The table below presents a listing of the symbols used in various modern Indian scripts for the numbers from zero to nine:
|Arabic Numerals||0||1||2||3||4||5||6||7||8||9||Used in|

A decimal place system has been traced back to ca. 500 in India. Before that epoch, the Brahmi numeral system was in use; that system did not encompass the concept of the place-value of numbers. Instead, Brahmi numerals included additional symbols for the tens, as well as separate symbols for hundred and thousand.
I will omit all discussion of the science of the Indians ... of their subtle discoveries in astronomy — discoveries that are more ingenious than those of the Greeks and the Babylonians - and of their valuable methods of calculation which surpass description. I wish only to say that this computation is done by means of nine signs. If those who believe that because they speak Greek they have arrived at the limits of science would read the Indian texts they would be convinced even if a little late in the day that there are others who know something of value.
The addition of zero as a tenth positional digit is documented from the 7th century by Brahmagupta, though the earlier Bakhshali Manuscript, written sometime before the 5th century, also included zero. But it is in Khmer numerals of modern Cambodia where the first extant material evidence of zero as a numerical figure, dating its use back to the seventh century, is found.
As it was from the Arabs that the Europeans learned this system, the Europeans called them Arabic numerals; the Arabs refer to their numerals as Indian numerals. In academic circles they are called the Hindu-Arabic or Indo-Arabic numerals.
The significance of the development of the positional number system is probably best described by the French mathematician Pierre Simon Laplace (1749–1827) who wrote:
It is India that gave us the ingenious method of expressing all numbers by the means of ten symbols, each symbol receiving a value of position, as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit, but its very simplicity, the great ease which it has lent to all computations, puts our arithmetic in the first rank of useful inventions, and we shall appreciate the grandeur of this achievement when we remember that it escaped the genius of Archimedes and Apollonius, two of the greatest minds produced by antiquity.
This long period of nearly five thousand years saw the rise and fall of many civilizations, each leaving behind a heritage of literature, art, philosophy, and religion. But what was the net achievement in the field of reckoning, the earliest art practiced by man? An inflexible numeration so crude as to make progress well nigh impossible, and a calculating device so limited in scope that even elementary calculations called for the services of an expert [...] Man used these devices for thousands of years without contributing a single important idea to the system [...] Even when compared with the slow growth of ideas during the dark ages, the history of reckoning presents a peculiar picture of desolate stagnation. When viewed in this light, the achievements of the unknown Hindu, who some time in the first centuries of our era discovered the principle of position, assumes the importance of a world event.
