#arithm
- Aliquant — A fractional part of a whole or of a number that does not divide it exactly, always leaving a remainder after the mathematical division operation. Unlike an aliquot part, an aliquant part is contained within a larger quantity a number of times plus a fraction (e.g., 5 is an aliquant part of 12, because it goes into it twice and leaves a remainder of 2). In old legal terminology, it described an unequal or residual share.
- Antilogarithm — A number whose logarithm value in a given base is equal to a considered number; the inverse operation of taking a logarithm, structurally representing the raising of the base to the power indicated by the logarithm. In a functional sense, if log base b of x equals y, then the antilogarithm of y in base b equals x, historically used in complex numerical calculations via tables.
- Arithm — A rare technical term used as a combining form or abstract structural unit referencing numbers, numerical calculation, or arithmetic operations. In computer science and automation, it can describe an elementary component within a computational algorithm focused exclusively on digit manipulation and quantitative data processing, independent of complex algebraic variables.
- Arithmetic — Pertaining to arithmetic, referring to arithmetic, or based on the fundamental operations and rules of numbers. In mathematics, the term qualifies a progression where each term is obtained by adding a constant ratio to the preceding term, or a calculation, operator, or mean obtained by summing elements and dividing them by their total number.
- Arithmetic — The oldest and most elementary branch of mathematics, dealing with the study of numbers, their properties, and fundamental operations such as addition, subtraction, multiplication, and division. In an educational sense, it represents the core school subject introducing primary numerical calculus, forming the foundation for advanced algebraic structures and number theory.
- Arithmetical — An archaic or regional adjectival form used in the past as a synonym for the modern term 'arithmetic'; relating to arithmetic, based on numerical calculation or the properties of numbers and elementary operations. This structural term is found in old mathematics textbooks or historical documents to describe rules, proportions, operations, or numerical progressions.
- Arithmetically — An archaic adverbial form used with the meaning 'from an arithmetical point of view' or 'arithmetically'; in accordance with the rules and methods of elementary numerical calculation. In old texts, this structural adverb indicated how a mathematical operation, quantitative evaluation, or proportional distribution of goods was to be executed.
- Arithmetician — A specialist in arithmetic; a mathematician dedicated to the study of numbers, their properties, and fundamental numerical operations. In a historical and academic sense, the term describes a person who masters the art of computation and numerical algorithms, contributing to the development of the theoretical foundations of elementary mathematics or number theory.
- Female arithmetician — A female specialist in arithmetic; a female mathematician concerned with the theoretical or applied study of numbers, their properties, and numerical operations. The term highlights the feminine presence and contribution in the field of exact sciences, designating a person highly qualified in the analysis of computational algorithms.
- Arithmophobia — A pathological, irrational, and persistent fear of numbers, digits, or performing arithmetic calculations. This specific anxiety disorder can manifest through panic attacks, sweating, and an intense desire to avoid situations involving interaction with statistical data, prices, phone numbers, or mathematical equations, significantly affecting the individual's daily and professional life.
- Arithmograph — An old mechanical apparatus or device used for automatically performing and graphically recording or printing primary arithmetic calculations. In the history of computing technology, the instrument represents an essential intermediate step between the abacus and modern electric calculating machines, used in accounting and statistics during the late 19th and early 20th centuries.
- Arithmography — A rare neologistic term designating the study, description, or graphical representation of numbers and the arithmetic relationships between them. In some historical or occult contexts, it may refer to a method of calculation or symbolic interpretation of texts by converting letters into numerical values, similar to gematria.
- Arithmogriph — A puzzle or crossword game in which letters are replaced by numbers according to a set key; a cryptogram or coded crossword. Solving it requires identifying the unique correspondence between each number and its associated letter to reconstruct the hidden words or message.
- Arithmology — The theoretical or philosophical study of numbers and the religious, mystical, or occult properties attributed to them, beyond their purely mathematical calculating value. In the history of science, the term often describes Pythagorean or Kabbalistic esoteric systems that interpreted the universe through a sacred numerical structure, but it can also denote an archaic branch dealing with the systematic classification of names and numerical concepts.
- Arithmomanic — A person (male) suffering from arithmomania, an obsessive-compulsive disorder manifested by the irresistible urge and pathological impulse to continuously count objects, words, steps, or daily actions, or to perform useless mathematical calculations. As an adjective, it describes behavior, a structural fixation, or an attitude characteristic of this obsessive neurosis.
- Arithmomaniac — A female person suffering from arithmomania; a woman affected by an obsessive-compulsive disorder manifested by an irresistible and pathological impulse to repeatedly count objects, actions, words, or elements in the surrounding environment. As an adjective, it describes a manifestation, attitude, or behavioral trait marked by the compulsive obsession with useless counting and mathematical calculations.
- Arithmomania — A form of obsessive-compulsive disorder (OCD) consisting of an individual's irresistible and obsessive need to count everything they see or hear, or to perform constant and useless mental mathematical calculations. Affected individuals feel deep anxiety if interrupted from this ritual, subconsciously believing that failing to complete the count (such as counting steps, building windows, or lampposts) can cause a disaster.
- Arithmometer — The first industrial mechanical calculating machine capable of performing the four fundamental arithmetic operations (addition, subtraction, multiplication, and division), patented in 1820 by the Frenchman Thomas de Colmar. This robust device, based on stepped drums with teeth of variable lengths, dominated administrative and banking offices worldwide for nearly a century, representing the technological grandfather of modern desktop calculators.
- Average — A term borrowed from English, used as a neologism in Romanian statistics, economics, computing, and business jargon to denote the mean value, arithmetic average, or the midpoint of a data set; as an adjective, it describes an element that falls within normal, ordinary, or mediocre limits, lacking exceptional or extreme features. In corporate environments, it is frequently used to evaluate performance or standardized metrics.
