Next: About this document Greek Numbers and Arithmetic The earliest numerical notation used by the Greeks was the Attic system. It employed the vertical stroke for a one, and symbols for ``5", ``10", ``100", ``1000", and ``10,000". Though there was some steamlining of its use, these symbols were used in a similar way to the Egyptian system, being that symbols were used repeatedly as needed and the system was non positional. By the Alexandrian Age, the Greek Attic system of enumeration was being replaced by the Ionian or alphabetic numerals. This is the system we discuss. The (Ionian) Greek system of enumeration was a little more sophisticated than the Egyptian though it was non-positional. Like the Attic and Egyptian systems it was also decimal. Its distinguishing feature is that it was alphabetical and required the use of more than 27 different symbols for numbers plus a couple of other symbols for meaning. This made the system somewhat cumbersome to use. However, calculation lends itself to a great deal of skill within almost any system, the Greek system being no exception. Greek Enumeration and Basic Number Formation First, we note that the number symbols were the same as the letters of the Greek alphabet.

Randomness in Arithmetic Scientific American 259, No. 1 (July 1988), pp. 80-85 by Gregory J. Chaitin It is impossible to prove whether each member of a family of algebraic equations has a finite or an infinite number of solutions: the answers vary randomly and therefore elude mathematical reasoning. What could be more certain than the fact that 2 plus 2 equals 4? Since the time of the ancient Greeks mathematicians have believed there is little-if anything-as unequivocal as a proved theorem. In fact, mathematical statements that can be proved true have often been regarded as a more solid foundation for a system of thought than any maxim about morals or even physical objects. The 17th-century German mathematician and philosopher Gottfried Wilhelm Leibniz even envisioned a ``calculus'' of reasoning such that all disputes could one day be settled with the words ``Gentlemen, let us compute!'' By the beginning of this century symbolic logic had progressed to such an extent that the German mathematician David Hilbert declared that all mathematical questions are in principle decidable, and he confidently set out to codify once and for all the methods of mathematical reasoning. This result, which is part of a body of work called algorithmic information theory, is not a cause for pessimism; it does not portend anarchy or lawlessness in mathematics. (Indeed, most mathematicians continue working on problems as before.) What it means is that mathematical laws of a different kind might have to apply in certain situations: statistical laws. In the same way that it is impossible to predict the exact moment at which an individual atom undergoes radioactive decay, mathematics is sometimes powerless to answer particular questions. Nevertheless, physicists can still make reliable predictions about averages over large ensembles of atoms. Mathematicians may in some cases be limited to a similar approach.

The library contains components for a variety of arithmetic operations and for different speed requirements. The library components are implemented as circuit generators in parameterized structural VHDL code. Their modular and well-documented source code allows for simple usage and easy customization. Highly efficient circuit architectures are used, which are optimized for synthesis and cell-based design. The VHDL library is platform independent, and it provides circuits with comparable performance, but higher flexibility and a larger diversity of arithmetic operations compared to commercial data path libraries.

Two disasters caused by computer arithmetic errors Patriot Missile Failure On February 25, 1991, during the Gulf War, an American Patriot Missile battery in Dharan, Saudi Arabia, failed to intercept an incoming Iraqi Scud missile. The Scud struck an American Army barracks and killed 28 soliders. A report of the General Accounting office, GAO/IMTEC-92-26, entitled Patriot Missile Defense: Software Problem Led to System Failure at Dhahran, Saudi Arabia reported on the cause of the failure. It turns out that the cause was an inaccurate calculation of the time since boot due to computer arithmetic errors. Specifically, the time in tenths of second as measured by the system's internal clock was multiplied by 1/10 to produce the time in seconds. This calculation was performed using a 24 bit fixed point register. In particular, the value 1/10, which has a non-terminating binary expansion, was chopped at 24 bits after the radix point. The small chopping error, when multiplied by the large number giving the time in tenths of a second, lead to a significant error. Indeed, the Patriot battery had been up around 100 hours, and an easy calculation shows that the resulting time error due to the magnified chopping error was about 0.34 seconds. (The number 1/10 equals 1/2 The following paragraph is excerpted from the GAO report.

69. Distributed Arithmetic Distributed arithmetic isn't magic. Distributed arithmetic is a bit levelrearrangement of a multiply accumulate to hide the multiplications. http://www.andraka.com/distribu.htm

Distributed Arithmetic isn't magic. Let's demystify it: Distributed arithmetic is a bit level rearrangement of a multiply accumulate to hide the multiplications. It is a powerful technique for reducing the size of a parallel hardware multiply-accumulate that is well suited to FPGA designs. It can also be extended to other sum functions such as complex multiplies, fourier transforms and so on. Look at my Radar on a chip paper for an application example of distributed arithmetic. The Derivation: In most of the multiply accumulate applications in signal processing, one of the multiplicands for each product is a constant. Usually each multiplication uses a different constant. Using our most compact multiplier, the scaling accumulator , we can construct a multiple product term parallel multiply-accumulate function in a relatively small space if we are willing to accept a serial input. In this case, we feed four parallel scaling accumulators with unique serialized data. Each multiplies that data by a possibly unique constant, and the resulting products are summed in an adder tree as shown below. If we stop to consider that the scaling accumulator multiplier is really just a sum of vectors, then it becomes obvious that we can rearrange the circuit.

Arithmetic is a branch of mathematics which records elementary properties of certain arithmetical operations on numbers . The traditional operations are addition subtraction multiplication , and division , although more advanced operations such as exponentiation and taking square roots are sometimes considered as well. The arithmetic of natural numbers integers rational numbers (in the form of fractions ) and real numbers (in the form of decimal expansions ) is typically studied by schoolchildren in elementary grades. Representations of numbers in terms of percentages are generally studied then as well. However, in adult life, most people rely on

Contacting the author Introduction Arithmetic coding, is entropy coder widely used, the only problem is it's speed, but compression tends to be better than Huffman can achieve. This presents a basic arithmetic coding implementation, if you have never implemented an arithmetic coder, this is the article which suits your needs, otherwise look for better implementations. Arithmetic coding The idea behind arithmetic coding is to have a probability line, 0-1, and assign to every symbol a range in this line based on its probability, the higher the probability, the higher range which assigns to it. Once we have defined the ranges and the probability line, start to encode symbols, every symbol defines where the output floating point number lands. Let's say we have: Symbol Probability Range a b c Note that the "[" means that the number is also included, so all the numbers from to 5 belong to "a" but 5. And then we start to code the symbols and compute our output number. The algorithm to compute the output number is: Low = High = 1 Loop. For all the symbols.

The Egyptian Zero Egyptian Counting Addition Subtraction ... Egyptian Fractions EYPTIAN COUNTING WITH HEIROGLYPHS These are the basic glyphs (symbols) used in Egypt for counting over 4000 years ago: Writing an integer consists of writing the number (from to 9) of the proper symbols to represent the integer. Thus, There is also a glyph which can translated as "equals" and a compact way of writing large glyphs, as shown below on the right, for two ways 35: in early Egypt Addition and subtraction were simple processes using the counting glyphs . To add two numbers, collect all symbols of similar type and replace a ten of one type by one of the next higher order. For example, adding 35 and 17: add Subtraction is a reversal of the process, if necessary replace a higher, so subtract Multiplication and Division Multiplication and Division were also simple processes using the counting glyphs . To multiply two numbers, all you needed to understand was the double or the half of an integer; i.e., the 2 times table.
