1 Marie Trudelle Professor Rosentrater Fundamentals of Math I 14 November 2013 The Formation of Numeral Systems Early primal civilization developed a means to keep track of days, food supply, village members, deaths, etc. These basic principles evolved into impressive numeration system with various rules and standards. Throughout this paper, the Chinese and Greek numeration system will be analyzed in depth. During an extensive archeological dig in Xiao dun, China, during the year 1899, remnants of the ancient Chinese numeration system were revealed.1 Markings of different numeral characters were inscribed into various mediums such as turtle shells, bones, and sticks.2 The data recorded, containing particulars about calendar dates, quantity of food stored, or amount of individuals killed in war proved to be valuable for the ancient society. Two structures of the Chinese numeration system were developed—the written character arrangement and the rod numeral method. The written character system came first and was followed by the rod approach in the 6th century B.C.3 Both procedures are founded in the base ten decimal place-notion system.4 Chinese numerals are characters that express numbers in print. Comparable to how numbers are sometimes written out in English, such as one hundred, the Chinese J.J O’Connor and E.F. Robertson. Chinese Numerals, (January 2004). J.J O’Connor and E.F. Robertson.

(2003). 1 2 2 characters ‘spell out’ the number.5 The first ten numbers would be pronounced, “yī èr sān sì wǔ liù qī bā jiǔ shí.”6 Chinese symbols are printed vertically with the highest place value at the top.7 Below is a Chinese numeral chart expressing Chinese characters and numbers respectively. J.J. O’Connor and E.F. Robertson. Chinese Numerals. (2004) The Chinese system is a slightly altered multiplicative procedure. Characters are to be read in pairs—one represents a number 1-9 while the lower number is always a power of ten.8 For example, 500 is illustrated by the character five and one hundred. While this technique continued into the thousands (8,000 was eight and one thousand), there are no signs of numbers greater than 30,000.9 Perhaps archeologists have been unable to locate evidence of large numbers or perhaps the Chinese never had a need for such numbers. While this system was mostly based off the multiplicative theory, there are two sectors that reveal refinement. The first alteration includes the one unit—it uses a single 5J.J O’Connor and E.F.

Just the symbol for 10 is written.”12 The written system also lacked the notion of zero.13 The Chinese numeral system was clear and used by members of society everyday. Hence, ‘basic’ calculators, called counting rods, were invented in the 6th century BC.14 The Chinese used bamboo rods and sticks to constitute numbers 1-9.15 The idea of rods was simplified into small counting boards, which were used like calculators. The boards were not only manipulated by the Chinese but also utilized by foreigners passing through the Silk Road.16 The counting boards revealed a number that was, “…formed in a row with the units placed in the right most column, the tens in the next column to the left, the hundreds in the next column to the left etc.”17 The rod system was simple and didn’t need to have a zero notion because the column would be left empty.18 Below is an image of a Chinese rod board and its natural place values. 10Addison-Wesley.

Development of Mathematics in Ancient China. The only confusion with the counting boards was misreading numbers because sometimes they were horizontal while other times vertical. The Chinese solved this issue by numbers in the units column were represented vertically and the numbers in the tens column were expressed horizontally.19 They proceeded to alternate between horizontal and vertical lines in higher number powers.20 In the image below the lower row would depict the one’s column and the top row reveals the tens column.

Both adopted a base ten decimal system as well as a place-notion system. The Chinese similarly developed nine symbols to represent 1-9 and then use a combination of those symbols to represent the remaining numbers.21Another similarity is the use of an empty set for zero. The Hindu Arabic system invented a symbol called the sunya, which ultimately conveys an empty set.22 The Hindu Arabic system was invented around 800 BC while the Chinese was formulated in 480 BC.23 Next, the Greek numeration system will be analyzed and highlight progress as well as areas of confusion. The Phoenicians invented the base 10 system in the year 900 BC.24 It first began with the Attic System, which was comparable to a tally system. This system became troublesome because the numbers were lengthy and individuals were forced to carve numbers possessing more than thirteen characters into stone.25 The Phoenicians then adopted a twenty-four letter alphabetic to represent various numerals.26 Unfortunately; however, in order for the Greek number system to function properly, twenty-seven letters were necessary. Therefore, three ancient symbols that were used in the old alphabet were reintroduced and represented the numbers six, ninety, and nine Lam Lay-Yong.

Digamma, xi, and sampi; however, are no longer used in the Greek numeration system.28 Therefore, commas are now placed before the letters when symbolizing numbers from 1,000 to 999, 999.29 (Represents 6 and its Greek name is digamma). (Represents 60 and its Greek name is xi) (Represents 900 and its Greek name is sampi) Similar to the Chinese, the Greeks gave each number, one through nine, a different symbol. They also gave higher numbers (10, 20, 30, 40… 100, 200, 300…) new symbols.30 While this prevented people from mixing up numbers, the society only invented a finite amount of numbers. Below is a chart of various Greek letters and their value. Carey Eskridge Lybarder, Number Systems. R. Andews, and K. Hysick. The Greek Number System. 29M.Lahanas, R. Andews, and K. Hysick.

(2004) Although, the Greeks simplified their system from the original Attic method, it is incredibly challenging to perform arithmetic. One must need to comprehend a large sum of Greek symbols in order to perform basic addition such as iota + iota = kappa.31 Multiplication was even more complex and individuals were forced to use the aid of an abacus.32 While the Babylonian system was established before the Greek, they opted to not use a positional number system.33 Their numeration system was based on the additive principle, so the number 241 would be composed by 200 + 40 + 1 or Jo Edkins. Greek Numbers. (2006) Jo Edkins. Greek Numbers. (2006) 33 Carey Eskridge Lybarder, Number Systems. 31 32 8 . Hence, the Greeks lacked a zero notion.34It is noted that, “Greek mathematicians did not need to name their numbers since they worked with numbers as lengths of lines.”35 While the Chinese and Greek systems are different they possess a handful of similar qualities. Both numeration systems are decimal base ten structures. They contain distinct symbols for numbers 1-9; however, the Greek system also invented new symbols to exhibit the tens, hundreds, etc. value. The Chinese system is remarkably easy to use and was implemented in the everyday life of merchants, scribes, and army officials. While it is mostly multiplicative is does possess a few additive properties. On the other hand, the Greek system is entirely additive but lacks a place value system. Both the Chinese and Greek have omitted the notion of zero, allowing other civilizations to ponder the abstract idea. Works Cited 34Carey 35 Eskridge Lybarder, Number Systems, J.J O’Connor and E.F.
