101. Babylonian Numerals Finally we should look at the question of why the Babylonians had a number system with a base of 60. The easy answer is that they inherited the base of 60 from the Sumerians but http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Babylonian_numerals.html

Babylonian numerals Babylonian index History Topics Index Version for printing 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.

A Brief Description of the Chinese Number System Traditional Simplified Formal Trad. (Daxie) Formal Simp. (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.

Next OCTAL NUMBER SYSTEM The octal, or base 8, number system is a common system used with computers. Because of its relationship with the binary system, it is useful in programming some types of computers. Look closely at the comparison of binary and octal number systems in table 1-3. You can see that one octal digit is the equivalent value of three binary digits. The following examples of the conversion of octal 225 to binary and back again further illustrate this comparison: Table 1-3. - Binary and Octal Comparison Unit and Number The terms that you learned in the decimal and binary sections are also used with the octal system. The unit remains a single object, and the number is still a symbol used to represent one or more units. Base (Radix) As with the other systems, the radix, or base, is the number of symbols used in the system. The octal system uses eight symbols - through 7. The base, or radix, is indicated by the subscript 8.

NUMBER SYSTEMS The Decimal (base-10) Number System Powers of 10 Evaluating a number in base-10 Example: 1,492.76 From this example, we see that the value of a number is the sum of the products of each digit multiplied by its positional value. That is, the 4 has a positional value of 100 (or 10 ), so its value is 400; 9 has a positional value of 10 (or 10 ), so its value is 90, and so. After we get the value of each digit, we add the values: 1,000 + 400 + 90 +2 + .7 + .06 = 1,492.76. The Binary (base-2) Number System Powers of 2 Evaluating a number in base-2 Example: 1010.11 In other words, evaluating a number is the same as in base-10, except that it is easier. Since one times any number is that number, and zero times any number is zero, we can rewrite our formula as: 1010.11 = 8+2+ , which equals 10.75 in base-10. Decimal to binary conversion One method of conversion is to use the powers of two, as in the above example. Another method is repeated division (also known as the quotient-and-remainder method). You divide repeatedly by 2, and each time the remainder becomes a digit in the binary number. Example: 29 in base-10 is equivalent to 11101 in base-2.

106. Number System Conversion - Explanation In a positional number system, the value of each digit is determined by which place it appears in the full number. The lowest place value is the rightmost http://courses.cs.vt.edu/~cs1104/number_conversion/convexp.html

CSTC home browse resources cover page content Conversion Between Different Number Systems Positional number systems Our decimal number system is known as a positional number system, because the value of the number depends on the position of the digits. For example, the number has a very different value than the number , although the same digits are used in both numbers. (Although we are accustomed to our decimal number system, which is positional, other ancient number systems, such as the Egyptian number system were not positional, but rather used many additional symbols to represent larger values.) In a positional number system, the value of each digit is determined by which place it appears in the full number. The lowest place value is the rightmost position, and each successive position to the left has a higher place value. In our decimal number system, the rightmost position represents the "ones" column, the next position represents the "tens" column, the next position represents "hundreds", etc. Therefore, the number represents hundred and tens and ones, whereas the number

116. The Classic Maya Calendar And Day Numbering System by L Count Related articles http://www.ece.udel.edu/~mills/maya.html

The Classic Maya Calendar and Day Numbering System Home Credentials Publications Projects ... Kin Introduction The calendar systems used in the ancient world reflect the agricultural, political and ritual needs characteristic of the societies in which they flourished. Astronomical observations to establish the winter and summer solstices were in use three to four millennia ago [1]. By the 14th century BCE the Shang Chinese had established the solar year as 365.25 days and the lunar month as 29.5 days. The lunisolar calendar, in which the ritual month is based on the Moon and the agricultural year on the Sun, was used throughout the ancient Near East (except Egypt) and Greece from the third millennium BCE. Early calendars used either thirteen lunar months of 28 days or twelve alternating lunar months of 29 and 30 days and haphazard means to reconcile the 354/364-day lunar year with the 365-day solar year. The study of historic and modern calendar systems is a fascinating adventure involving interlocking political, religious and economic agendas. A reconciliation of the various modern calendar systems suffered by computer systems of the world is given in [2]. The conciliation adopted by the Network Time Protocol is given in [3]. The following discussion of the Classic Maya calendar is based on the comprehensive history of the Maya given in [5]. Before we start, a note on the terms of reference. The term Maya is used by historians as both a noun and an adjective to refer to the people, their culture and their artifacts. However, there are many related languages of the Maya; therefore, historians use the term
