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. The Babylonians assigned this number to Marduk.The Indian numerals discussed in our article Indian numerals form the basis of the European number systems which are now widely used. This represents An's status as the ruler of the cosmos and the king of the gods.ĥ0: Enlil. The sacred numbers of primary deities are as follows:Ħ0 or 1: An. The presence of these numbers in a person's life, or repeatedly seeing the same numbers, could indicate that a deity is trying to communicate, or that the areas of life represented by that deity's domains are in need of attention. The most powerful and revered deities have numbers that are factors of 60, or that are in some way mathematically useful. Some numbers are associated with gods, to the extent that they could stand in for a god's name in certain cases □□□ (the "divine" determinative + "15") is for example considered a valid spelling for Inana. 3600, which is 60*60, was the number of the universe, the totality of existence - both "3600" and "everything" translate as □ šar. Sumerian fractions are typically based on the denominator 6 and are as follows:Ħ0 was seen as a number of wholeness and completion. They continued to always be written horizontally when followed by a unit of measure. In earlier texts, the ‘unit’ digits 1 through 9 were usually seen written horizontally □, □, □. The pronunciations of numbers above 60 are not written out in Sumerian and are uncertain the above table is one reconstruction of how they may have been pronounced in early Sumerian. The Sumerians did not focus much on abstract mathematics and the populations of their cities were much lower than ours they seldom needed to count 432,000 of anything. Numbers above 432,000 are unattested in ancient Sumerian (with one exception: 60*216,000 = 12,960,000, seen as a holy number from which all others derive). This has the advantage over the later Babylonian system of ensuring total unambiguity over which number is meant to be written.Ħ0: geš □ (note this stroke is thicker than diš □)Ģ16,000: geššar □ or □ (later šar-gal, “great šar”) Like the Babylonian system, which it inspired, the Sumerian place values increase in alternating steps of x10 and 圆: there are different symbols for 1, 10, 60, 600, 3600, 36000, and 216000, and other numbers are formed by combining groups of these symbols. The Sumerian numeral system differs from the perhaps better known Babylonian one in that Sumerian has different symbols for each place value. Later, the symbols on these tokens were embossed into clay using a round stylus, and eventually these symbols were adopted so they could be embossed using the regular reed stylus used to write other cuneiform signs. The origins of the Sumerian numeral system lie in a system of tokens used to count commodities. This is the origin of our 60 minutes in an hour, 60 seconds in a minute, and 360 (6*60) degrees in a circle. They worked in base 60 - a sexagesimal system. The Sumerians were perhaps the first people to decipher the basics of mathematics.
