# Topic: Elementary arithmetic

###### In the News (Wed 17 Jul 19)

 Encyclopedia :: encyclopedia : Elementary arithmetic (via CobWeb/3.1 planetlab2.cs.unc.edu)   (Site not responding. Last check: 2007-10-12) Elementary arithmetic is the most basic kind of mathematics: it concerns the operations of addition, subtraction, multiplication, and division. Elementary arithmetic starts with the natural numbers and the Arabic numerals used to represent them. Though starting out with natural numbers, elementary arithmetic then moves on to fractions, then decimals and negative numbers, which can be represented on a number line. www.hallencyclopedia.com.cob-web.org:8888 /topic/Elementary_arithmetic.html   (4036 words)

 Arithmetic Summary Arithmetic is a branch of mathematics concerned with the numerical manipulation of numbers using the operations of addition, subtraction, multiplication, division, and the extraction of roots. Arithmetic or arithmetics (from the Greek word αριθμός = number) is the oldest and simplest branch of mathematics, used by almost everyone, for tasks ranging from simple daily counting to advanced science and business calculations. Algorism comprises all of the rules of performing arithmetic computations using a decimal system for representing numbers in which numbers written using ten symbols having the values 0 through 9 are combined using a place-value system (positional notation), where each symbol has ten times the weight of the one to its right. www.bookrags.com /Arithmetic   (3476 words)

 What Is Arithmetic? Arithmetic is a branch of mathematics that deals with properties of the counting (and also whole) numbers and fractions and the basic operations applied to these numbers. The distinction between arithmetic and algebra that underscores the use of letters is valid on an elementary level. Elementary algebra, a step ahead of arithmetic, does use letters for formulating and solving problems and to annunciate properties of the arithmetic operations in a general form. www.cut-the-knot.org /WhatIs/WhatIsArithmetic.shtml   (757 words)

 Elementary arithmetic - Wikipedia, the free encyclopedia Elementary arithmetic then moves on to fractions, decimals, and negative numbers, which can be represented on a number line. In ancient times, the abacus was often used to perform elementary arithmetic. Elementary school children are taught to subtract using methods suitable for hand calculation. en.wikipedia.org /wiki/Elementary_arithmetic   (4648 words)

 What Is Algebra? Elementary Algebra that follows the study of arithmetic is mostly occupied with operations on sets of whole and rational numbers and solving first and second order equations. What puts elementary algebra step ahead of elementary arithmetic is a systematic use of letters to denote generic numbers. Mastering of elementary algebra which is often hailed as a necessary preparatory step for the study of Calculus, is as often an insurmountable block in many a career. www.cut-the-knot.org /WhatIs/WhatIsAlgebra.shtml   (270 words)

 Arithmetic - Wikipedia, the free encyclopedia Arithmetic or arithmetics (from the Greek word αριθμός = number) is the oldest and most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple daily counting to advanced science and business calculations. The prehistory of arithmetic is limited by a very small number of small artifacts indicating a clear conception of addition and subtraction, the best-known being the Ishango Bone from Africa, dating from 18,000 BC. Modern algorithms for arithmetic (both for hand and electronic computation) were made possible by the introduction of Arabic numerals and decimal place notation for numbers. en.wikipedia.org /wiki/Arithmetic   (1385 words)

Cross-references: identity, additive, one-to-one, function, successor, axioms, Peano arithmetic, induction, arithmetic, theory This is version 2 of Elementary Functional Arithmetic, born on 2002-08-17, modified 2002-08-17. planetmath.org /encyclopedia/ElementaryFunctionalArithmetic.html   (85 words)

 Arithmetic Methods Arithmetic methods rely on the four elementary arithmetic operations: addition, subtraction, multiplication, and division. Arithmetic is taught in grammar school, and the algebraic notions required are really just first-year high school algebra. It is the abstruseness of the arithmetic expression that repels the incompetent and attracts the perfectionist. www.erasmatazz.com /library/JCGD_Volume_1/Arithmetic_Methods.html   (841 words)

 Arithmetic: A Crash Review Now, consider the sentence "One plus one is two." [This is the arithmetic statement corresponding to the first statement.] Here, the object of the sentence is "two"...so "two" must be used as a noun.

 Aerotek Elementary Binary Arithmetic A glance into the dictionary reveals the word binary to mean "characterized by two things or parts." From this, we may infer, correctly, that binary arithmetic is in some way associated with the figure 2. In explaining the elements of binary arithmetic in this article, frequent comparisons will be made with the decimal system for the sake of clarity or proof. After studying the rudiments of binary arithmetic presented here, the reader should be able, by setting up for himself a number of practice examples for drill, to acquire considerable proficiency in manipulating this invaluable new tool. www.decodesystems.com /aerovox.html   (1541 words)

 Abolish P-and-P Arithmetic This article proposes that paper-and-pencil arithmetic no longer be taught in elementary school and that it be replaced by a curriculum which emphasizes mental arithmetic much more than at present and in which calculators are used for instructional purposes in all grades including kindergarten. It is, after all, agreed by almost everyone that the incessant drill-and-practice in arithmetic, which for many years was the hallmark of elementary school mathematics almost everywhere and still is in many places, does not instill much understanding of arithmetic, however much mechanical proficiency may be its result. Of course, it is obvious that the mental arithmetic portion of the curriculum must be assessed in a non-calculator environment as must also the application of mental arithmetic in problem solving. www.doc.ic.ac.uk /~ar9/abolpub.htm   (7940 words)

 [No title] Perhaps you've heard of the Gentzen proof of the consistency of elementary arithmetic, given that epsilon-0 is a well-ordering. Gentzen was able to assign an ordinal under epsilon-0 to each proof in elementary arithmetic, and give a procedure for reducing a proof of a contradiction to a proof of a contradiction whose ordinal is smaller. Every true statement of arithmetic has an infinite branching proof tree in a system much like elementary arithmetic but with the omega rule. www.math.niu.edu /~rusin/known-math/99/gentzen   (473 words)

 A formal theory for arithmetic   (Site not responding. Last check: 2007-10-12) By arithmetic we mean elementary school arithmetic, i.e., the study of the positive whole numbers 1, 2, 3,... There are several methods of coping with the incompleteness phenomenon, and this constitutes a currently active area of research in foundations of mathematics. The contrast between the completeness of formal geometry and the incompleteness of formal arithmetic is striking. www.math.psu.edu /simpson/papers/philmath/node16.html   (347 words)

 Can You Solve This Paradox? Mind Over Mathematics -- Elementary Arithmetic His arithmetic teacher had assigned the students, the mind-busying task of adding up the whole numbers, from 1 to 100. The students were to do their calculations at their desks, on small slates, and, when finished, place their slates on a table in the middle of the room, so the slate of the first one finished, would be at the bottom of the pile. He finds himself free to inquire anew, beginning first with those elementary principles, which, never simple (except to the simple-minded), unfold a rich bounty of profound ideas, if the underlying, seemingly subtle, paradoxes are sought out. members.tripod.com /~american_almanac/elemen.htm   (3698 words)

 Prosp elementary teachers Prospective elementary teachers' mathematical knowledge of rational numbers was assessed during the first and second years of the project. The main conclusion we draw from this part of the research is that elementary arithmetic topics should be included in the curriculum of the teachers' colleges, but considered from a different perspective. In respect to rational numbers, it is essential that the curricula for elementary school teachers attempt to increase their familiarity with common representations of and with them; boost their understanding of the similarities and differences of these representations, and their ability to use them flexibly. jwilson.coe.uga.edu /Texts.Folder/Tirosh/Pros.El.Tchrs.html   (5416 words)

 Elementary Arithmetic The first and most important consideration is the choice of number representation for arithmetic calculations. There are two ways to do this: you can divide it by 100 and add the result to the original value; or you can multiply by 101 and then divide by 100. This is what separates the flight-simulation men from the boys: the cleverness to create adequate flight models that work with integer arithmetic. www.erasmatazz.com /library/JCGD_Volume_4/Elementary_Arithmetic.html   (1422 words)

 Operations and Elementary Functions Abstract: Decimal arithmetic is the norm in human calculations, and human-centric applications must use a decimal floating-point arithmetic to achieve the same results. Abstract: A means is described for performing arithmetic on zoned decimal data that does not require additional storage space for the intermediate result, and which preserves both operands until it is determined that the operation has been performed correctly and successfully. Particular attention is paid to the material of arithmetic which continues to be taught in our elementary schools and to the historical phases of that work with which the teacher of arithmetic should be familiar... www2.hursley.ibm.com /decimal/decbiboperation.html   (5511 words)

 Arbitrary-Precision Arithmetic Implementations in C of a high-precision calculator with all four elementary operations appear in [BR95]. The authors use base 10 for arithmetic and arrays of digits to represent long integers, with short integers as array indices, thus limiting computations to 32,768 digits. Notes: Knuth [Knu81] is the primary reference on algorithms for all basic arithmetic operations, including implementations of them in the MIX assembly language. www2.toki.or.id /book/AlgDesignManual/BOOK/BOOK4/NODE144.HTM   (1500 words)

 The Proposed Mathematics Curriculum For Elementary Schools In Israel I also limited myself mainly to the arithmetic part, since this is the main body of knowledge the student should acquire in elementary school. It is commonly accepted that at the end of elementary school the student should have a deep understanding of the four basic arithmetic operations. As to arithmetic operations, one problem of the curriculum for Grade 1 is that it does not stress their "meaning" aspect. www.math.technion.ac.il /~ra/ra-curr2000.html   (9095 words)

 Elementary Mathematics for Teachers Elementary Mathematics for Teachers is a textbook for a semester or two-quarter university course for pre-service teachers.

 [No title] Although my children attended a private elementary school at which calculators were not used, as soon as they began attending public school in junior high and high school, calculators appeared.... Teaching arithmetic with calculators is like saying we will do physical training by going for 20 km each day, then driving the 20 km in a car daily. In my view, the teaching of basic arithmetic skills is not an option for schools, but rather an important part of their mandate. www.math.jhu.edu /~wsw/ED/list   (3481 words)
