Extractions: Computer uses the binary system. Any physical system that can exist in two distinct states (e.g., 0-1, on-off, hi-lo, yes-no, up-down, north-south, etc.) has the potential of being used to represent numbers or characters. A binary digit is called a bit . There are two possible states in a bit, usually expressed as and 1. A series of eight bits strung together makes a byte , much as 12 makes a dozen. With 8 bits, or 8 binary digits, there exist 2^ =256 possible combinations. The following table shows some of these combinations. (The number enclosed in parentheses represents the decimal equivalent.) =1024 is commonly referred to as a "K". It is approximately equal to one thousand. Thus, 1 Kbyte is 1024 bytes. Likewise, 1024K is referred to as a "Meg". It is approximately equal to a million. 1 Mega byte is 1024*1024=1,048,576 bytes. If you remember that 1 byte equals one alphabetical letter, you can develop a good feel for size. You may regard each digit as a box that can hold a number. In the binary system, there can be only two choices for this number either a "0" or a "1". In the octal system, there can be eight possibilities:
Number System Conversion - Explanation
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.
http://www.cstc.org/data/resources/60/convexp.html

Extractions: 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

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).

http://www.thekeep.org/~kunoichi/kunoichi/themestream/egypt_maths.html

Extractions: The Ancient Egyptian Number System In ancient Egypt mathematics was used for measuring time, straight lines, the level of the Nile floodings, calculating areas of land, counting money, working out taxes and cooking. Maths was even used in mythology - the Egyptians figured out the numbers of days in the year with their calendar . They were one of the ancient peoples who got it closest to the 'true year', though their mathematical skills. Maths was also used with fantastic results for building tombs, pyramids and other architectural marvels. A part of the largest surviving mathematical scroll, the Rhind Papyrus (written in hieratic script), asks questions about the geometry of triangles. It is, in essence, a mathematical text book. The surviving parts of the papyrus show how the Egyptian engineers calculated the proportions of pyramids as well as other structures. Originally, this papyrus was five meters long and thirty three centimeters tall. It is again to the Nile Valley that we must look for evidence of the early influence on Greek mathematics. With respect to geometry, the commentators are unanimous: the mathematician-priests of the Nile Valley knew no peer. The geometry of Pythagoras, Eudoxus, Plato, and Euclid was learned in Nile Valley temples. Four mathematical papyri still survive, most importantly the Rhind mathematical papyrus dating to 1832 B.C. Not only do these papyri show that the priests had mastered all the processes of arithmetic, including a theory of number, but had developed formulas enabling them to find solutions of problems with one and two unknowns, along with "think of a number problems." With all of this plus the arithmetic and geometric progressions they discovered, it is evident that by 1832 B.C., algebra was in place in the Nile Valley.

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.

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.

Extractions: Bottom of This Page Hexadecimal Number System The Hexadecimal Number Base System A big problem with the binary system is verbosity. To represent the value 202 requires eight binary digits. The decimal version requires only three decimal digits and, thus, represents numbers much more compactly than does the binary numbering system. This fact was not lost on the engineers who designed binary computer systems. When dealing with large values, binary numbers quickly become too unwieldy. The hexadecimal (base 16) numbering system solves these problems. Hexadecimal numbers offer the two features: Since we'll often need to enter hexadecimal numbers into the computer system, we'll need a different mechanism for representing hexadecimal numbers since you cannot enter a subscript to denote the radix of the associated value. The Hexadecimal system is based on the binary system using a Nibble or 4-bit boundary. In Assembly Language programming, most assemblers require the first digit of a hexadecimal number to be 0, and we place an H at the end of the number to denote the number base. The Hexadecimal Number System: uses base 16 includes only the digits through 9 and the letters A, B, C, D, E, and F
