A calculation is a deliberate process for transforming one or more inputs into one or more results, with variable change.

The term is used in a variety of senses, from the very definite arithmetical calculation using an algorithm to the vague heuristics of calculating a strategy in a competition or calculating the chance of a successful relationship between two people. Arithmetic or arithmetics (from the Greek word αριθμός = number is the oldest and most elementary branch of mathematics used by almost everyone In Mathematics, Computing, Linguistics and related subjects an algorithm is a sequence of finite instructions often used for Calculation heuristic (hyu̇-ˈris-tik is a method to help solve a problem commonly an informal method

Multiplying 7 by 8 is a simple algorithmic calculation.

Estimating the fair price for financial instruments using the Black-Scholes model is a complex algorithmic calculation. Financial instruments are cash evidence of an ownership interest in an entity or a contractual right to receive or deliver cash or another financial instrument The term Black–Scholes refers to three closely related concepts The Black–Scholes model is a mathematical model of the market for an equity in which the equity's

Statistical estimations of the likely election results from opinion polls also involve algorithmic calculations, but give results that are ranges of possibilities rather than exact answers. Estimation theory is a branch of Statistics and Signal processing that deals with estimating the values of parameters based on measured/empirical data

Deciding the best way to build a relationship with a member of the opposite sex may also result from a calculation, but is not definite, predictable, nor even clearly defined. This indefinite application of the term gives it a second area of meaning apart from the mathematical senses mentioned above. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and

To calculate means to ascertain by computing. The English word derives from the Latin calculus, which originally meant a small stone in the gall-bladder (from Latin calx). Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. It also meant a pebble used for calculating, or a small stone used as a counter in an abacus (Latin abacus, Greek abax). An abacus, also called a counting frame, is a calculating tool used primarily by Asians for performing arithmetic processes Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly The abacus was an instrument used by Greeks and Romans for arithmetic calculations, preceding the slide-rule and the electronic calculator, and consisted of perforated pebbles sliding on an iron bars.
