If those who believe, because they speak Greek, that 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. I wish only to say that this computation is done by means of nine signs. , 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 will omit all discussion of the science of the Indians. In 662 AD Severus Sebokht, a Nestorian bishop who lived in Keneshra on the Euphrates river, wrote:. The first sign that the Indian numerals were moving west comes from a source which predates the rise of the Arab nations. For example there were at least three different types of arithmetic used in Arab countries in the eleventh century: a system derived from counting on the fingers with the numerals written entirely in words, this finger-reckoning arithmetic was the system used for by the business community the sexagesimal system with numerals denoted by letters of the Arabic alphabet and the arithmetic of the Indian numerals and fractions with the decimal place-value system. Rather different number systems were used simultaneously in the Arabic world over a long period of time. There are other complications in the story, however, for it was not simply that the Arabs took over the Indian number system. Transmission to Europe came through this western Arabic route, coming into Europe first through Spain. By the western part of the Arabic world we mean the regions comprising mainly North Africa and Spain. The eastern and western parts of the Arabic world both saw separate developments of Indian numerals with relatively little interaction between the two. The story of this transmission is not, however, a simple one. However they were not transmitted directly from India to Europe but rather came first to the Arabic/Islamic peoples and from them to Europe. How 3, 193, 619 3,\!193,\!619 3, 193, 619 looks if you are a Mayan.The Indian numerals discussed in our article on Indian numerals at THIS LINK form the basis of the European number systems which are now widely used. Let's see how it looks using Mayan numeral symbols. It doesn't look good this way because we were using the digits of a decimal system. That's it! The series of remainders is the number written in the new basis. Follow the steps until the integer quotient is 0.Take the integer quotient from the previous operation and divide again by 20.Take a number - any number, as big as you like - and follow these steps! If you want to learn something more about bases, check our other tools: Babylonians used base-60, as we've seen in our babylonian numbers converter, that's why there are 60 minutes in an hour and various cultures used base-20. The device you are reading on right now operates in base-2 (using only 1s and 0s), and through history, humans tried other bases. Now, the fact that 10 is usually also the number of fingers in your hands □□ is not a coincidence! Base-10 makes counting on your hands easier. Fun fact: Arabic numerals actually come from India!Ī fundamental feature of any numeral system is the base: the amount of numerals used to represent any number. Easy to understand, with space for a decimal separator and a placeholder (0), it quickly overtook other systems. Nowadays, Arabic numerals are the most used around the world. Counting is more widespread than we usually think, and many animal species are pretty good at simple maths! We (humans) are no exception, and since the time of our great-great-.-great-grandmas, our species evolved a deep understanding of that field: go ask the Egyptians with their Egyptian fractions! We are not sure whether it's a good thing or not, but young humans are the only ones wondering if they really need trigonometry in their lives.
