(Daxie) Pinyin While China has for many uses adopted the Arabic numeral system familiar around the world, it also still uses its native Chinese character number system. The Chinese system is also a base-10 system, but has important differences in the way the numbers are represented. Chinese has characters for numbers through 9, as seen above. In addition to the character shown above for zero, a simple circle is also used. Pronunciation for the characters uses the standard Romanization scheme in China called "pinyin" . The number at the end of the pinyin indicates the tone. Eleven in Chinese is "ten one". Twelve is "ten two", and so on. Twenty is "Two ten", twenty-one is "two ten one" (2*10 + 1), and so on up to 99. One-hundred is "one hundred". One-hundred and one is "one hundred zero one". One hundred and eleven is "one hundred one ten one". Notice that for eleven alone, you only need "ten one" and not "one ten one", but when used in a larger number (such as 111), you must add the extra "one". One thousand and above is done in a similar fashion, where you say how many thousands you have, then how many hundreds, tens, and ones. An exception to this is for zeroes. When a zero occurs in the number (except at the end), you need to say "zero", but only once for two or more consecutive zeroes. So one-thousand and one would be "one thousand zero one", where zero stands in for the hundreds and tens places. Try different numbers in the converter above to practice and check on other numbers.

Extractions: This courseware uses HTML 3.0 extensions Introduction A number system defines a set of values used to represent quantity. We talk about the number of people attending class, the number of modules taken per student, and also use numbers to represent grades achieved by students in tests. Quantifying values and items in relation to each other is helpful for us to make sense of our environment. We do this at an early age; figuring out if we have more toys to play with, more presents, more lollies and so on. The study of number systems is not just limited to computers. We apply numbers every day, and knowing how numbers work will give us an insight into how a computer manipulates and stores numbers. Mankind through the ages has used signs or symbols to represent numbers. The early forms were straight lines or groups of lines, much like as depicted in the film Robinson Crusoe , where a group of six vertical lines with a diagonal line across represented one week. Its difficult representing large or very small numbers using such a graphical approach. As early as 3400BC in Egypt and 3000BC in Mesopotamia, they developed a symbol to represent the unit 10. This was a major advance, because it reduced the number of symbols required. For instance, 12 could be represented as a 10 and two units (three symbols instead of 12 that was required previously).

Extractions: Recommend this site Abacus abacus to the Phoenician abak (sand). American Heritage Dictionary points to the Greek word abax , which might have originated from Hebrew avak (dust). There is little doubt that Ancients used a flat surface with sand strewn evenly over it as a disposable tool for writing and counting. It's said that the great Archimedes was slain by a Roman soldier while concentrating on figures drawn in sand. Later day abaci had grooves for small pebbles and later yet wires or rods on which counters could freely move back and forth. Each wire corresponded to a digit in a positional number system , commonly in base 10. A very curious state of affairs was mentioned by M. Gardner with a reference to K.Menninger. For more than 15 centuries the Greek and Romans and then Europeans in the Middle Ages and early Renaissance calculated on devices with authentic place-value system in which zero was represented by an empty line, wire or groove. Yet the written notations did not have a symbol for zero until it was borrowed by Arabs from Hindus and eventually introduced into Europe in 1202 by Leonardo Fibonacci of Piza in his Liber Abaci The Book of Abacus ). According to D. Knuth, counting with abaci was so convenient and easy that, at the time when only few knew how to write, it might have seemed preposterous to scribble some symbols on expensive papyrus when an excellent calculating device was readily available.

http://www-gap.dcs.st-and.ac.uk/~history/HistTopics/Greek_numbers.html

Extractions: There were no single Greek national standards in the first millennium BC. since the various island states prided themselves on their independence. This meant that they each had their own currency, weights and measures etc. These in turn led to small differences in the number system between different states since a major function of a number system in ancient times was to handle business transactions. However we will not go into sufficient detail in this article to examine the small differences between the system in separate states but rather we will look at its general structure. We should say immediately that the ancient Greeks had different systems for cardinal numbers and ordinal numbers so we must look carefully at what we mean by Greek number systems. Also we shall look briefly at some systems proposed by various Greek mathematicians but not widely adopted. The first Greek number system we examine is their acrophonic system which was use in the first millennium BC. 'Acrophonic' means that the symbols for the numerals come from the first letter of the number name, so the symbol has come from an abreviation of the word which is used for the number. Here are the symbols for the numbers 5, 10, 100, 1000, 10000.

http://www-gap.dcs.st-and.ac.uk/~history/HistTopics/Babylonian_numerals.html

Extractions: The Babylonian civilisation in Mesopotamia replaced the Sumerian civilisation and the Akkadian civilisation. We give a little historical background to these events in our article Babylonian mathematics . Certainly in terms of their number system the Babylonians inherited ideas from the Sumerians and from the Akkadians. From the number systems of these earlier peoples came the base of 60, that is the sexagesimal system. Yet neither the Sumerian nor the Akkadian system was a positional system and this advance by the Babylonians was undoubtedly their greatest achievement in terms of developing the number system. Some would argue that it was their biggest achievement in mathematics. Often when told that the Babylonian number system was base 60 people's first reaction is: what a lot of special number symbols they must have had to learn. Now of course this comment is based on knowledge of our own decimal system which is a positional system with nine special symbols and a zero symbol to denote an empty place. However, rather than have to learn 10 symbols as we do to use our decimal numbers, the Babylonians only had to learn two symbols to produce their base 60 positional system. Now although the Babylonian system was a positional base 60 system, it had some vestiges of a base 10 system within it. This is because the 59 numbers, which go into one of the places of the system, were built from a 'unit' symbol and a 'ten' symbol.

Note: Chapter 3 of Waites and Knott's book contains a series of major errors, I have compiled a list of these errors Having grown up with decimal number we all tend to take then for granted. However in our study of computers we need to use number which differ from the decimal (base 10). Lets look in detail at a decimal number system and recall the 'rules' associated with this system. First consider the following decimal number: 136.25. What does this actually mean? In its full incantation this number means: * 5 = 0.05 total = 136.25 Now consider the binary number 1101.01. Again in its full form this means: * 1 = 1000.0 (8 in decimal) 2 * 1 = 100.0 (4 in decimal) 2 * = 00.0 (0 in decimal) 2 * 1 = 1.0 (1 in decimal) 2 * = 0.0 (0.0 in decimal) 2 * 1 = 0.01 (0.25 in decimal) total = 1101.01 (13.25 in decimal) The following shows the first integers and their binary equivalents (and how they are derived): decimal binary 0000 (0 * 2 Just as decimal numbers can be added together to give a new value two binary numbers can be added together. The basic rules are:

http://www.wam.umd.edu/~tlaloc/archastro/ae26.html

Extractions: by Jose Barrios Garca In the 14-15th centuries Grand Canary and Tenerife were inhabited by Berber populations, called Canarians and Guanches. They presumably came from the nearby continent on different occasions between the first millennium BC and the first millennium AD. These populations remained relatively isolated until the European rediscovery of the Islands in late 13th century. At this time the population of each Island was about 40-60,000 inhabitants, sustaining a developed agricultural (barley, wheat) and stock raising (goats, sheep, pigs) economy. Written sources from c. 1300 AD on certify the arithmetical and calendrical activities of these groups. On this basis, I started the research on the mathematical and astronomical practices of these people that crystallized into my doctoral dissertation (editors note: congratulations to Jose for his recent defense of thesis at the University of La Laguna, Tenerife). For each Island the study considered: 1) the economical, social, political and religious organization of the Island 2) the written and archaeological evidence regarding numerical and calendrical activities 3) the economic and cultural context of the number systems and the calendars.
