A Math Forum Project Math Forum K-12 Math Puzzles Problems of the Week Student Center For many years mathematicians, scientists, engineers and others interested in mathematics have played "year games" via e-mail and in newsgroups. We don't always know whether it is possible to write expressions for all the numbers from 1 to 100 using only the digits in the current year, but it is fun to try to see how many you can find. This year may prove to be a challenge. As with many games, the rules for the Year Game can vary slightly. Teachers may wish to use different rules in their own classrooms. This Web page is intended for students in grades three through twelve with a general knowledge of mathematics. rules carefully if you wish to have your solutions posted on this site. Teachers may print out worksheets for students to record their findings, or may print sheets of manipulatives for students to use. Student solutions may be submitted starting January 1, 2001, using the Web form at the bottom of this page. We will begin to post student solutions after February 1, 2001. Student names, school names, and grades will appear as you enter them if your solution is posted. Your e-mail address will not appear on the Web page.

Arithmetic From Wikipedia, the free encyclopedia. Arithmetic is a branch of (or the forerunner of) mathematics which records elementary properties of certain operations on numerals The traditional arithmetic operations are addition subtraction multiplication and division , although more advanced operations (such as manipulations of percentages square root exponentiation , and logarithmic functions ) are also sometimes included in this subject. Arithmetic is performed according to an order of operations The arithmetic of natural numbers integers rational numbers (in the form of fractions ), and real numbers (using the decimal place-value system known as algorism ) is typically studied by schoolchildren, who learn manual algorithms for arithmetic. However, in adult life, many people prefer to use tools such as calculators computers , or the abacus to perform arithmetical computations. The term arithmetic is also used to refer to number theory . This includes the properties of integers related to primality divisibility , and the solution of equations by integers, as well as modern research which is an outgrowth of this study.

Modular arithmetic From Wikipedia, the free encyclopedia. In mathematics modular arithmetic is a system of arithmetic for certain equivalence classes of integers , called congruence classes . Sometimes it is suggestively called ' clock arithmetic ', where numbers 'wrap around' after they reach a certain value (the modulus ). For example, when the modulus is 12, then any two numbers that leave the same remainder when divided by 12 are equivalent (or "congruent") to each other. The numbers are all "congruent modulo 12" to each other, because each leaves the same remainder (2) on division by 12. The collection of all such numbers is a congruence class. As explained below, one can add such congruence classes to get another such congruence class, subtract two such classes to get another, and multiply such classes to get another. When the modulus is a prime number , one can always divide by any class not containing 0.

Composite numbers are numbers we get by multiplying together other numbers. For example, We say that 2 and 3 are factors of 6 (or, equivalently, that they are divisors of 6). Some numbers, however, have no factors other than themselves and one. Such numbers are called prime , and there are infinitely many of these. The Fundamental Theorem of Arithmetic (FTA) tells us something important about the relationship between composite numbers and prime numbers. It is usually stated as follows: Every natural number is either prime or can be uniquely factored as a product of primes in a unique way. unique.

Feel free to browse around, there is not much here at the moment... that's not to say that one day there will be something here! What is here is mostly for my benefit, not yours. :p However, since you came all this way, let me tell you a bit about myself: I am a pure mathematician, more specifically, I am an arithmetic geometer, well, more truthfully, a budding arithmetic geometer. I am Australian. I was born in Cambridge, UK. I grew up in Hobart, Tasmania (Australia). I completed my undergraduate studies in mathematics at the University of Melbourne. After which I did a Master's degree (in mathematics, of course) at Macquarie University, Sydney, Australia. I am now a first year PhD student in mathematics at Princeton University, Princeton, NJ, USA. My avocation from number theory is progressive DJing. Sooner or later I'll include some streams and pictures of my DJing exploits. I'm also an avid weightlifter, and I enjoy doing various martial arts: Tae Kwon-Do, Kung-Fu, and I dabble in Brazilian Jui Jitsu. Though various injuries have prevented me from doing so for a while.

A Research Training Network of the European Union Overview Partners Programme Positions Activities Project overview Developing powerful methods taken from geometry to study the arithmetical properties of algebraic equations Algebraic equations and their arithmetical properties have interested mankind since antiquity. One has only to think of the works of Pythagoras and Diophantus, which were a milestone in their time. For many centuries such problems have fascinated both serious mathematicians (Fermat, Gauss, ...) and amateurs alike. However, developments in recent years have transformed the subject into one of the central areas of mathematical research, which has relations with, or applications to, virtually every mathematical field, as well as an impact to contemporary everyday life (for example, the use of prime numbers and factorisation for encoding "smart" cards). The classical treatment of equations by analysis and geometry in the realm of complex numbers in this century has found a counterpart, in the similar theories over finite and p -adic fields, which have particular significance for arithmetic questions. The study of certain functions encoding arithmetic information and generalising the Riemann zeta-function (

"Arithmetic coding" by Arturo San Emeterio Campos Download Download the whole article zipped. Table of contents Introduction Arithmetic coding Implementation Underflow ... 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.
