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 of 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.

For example, multiplying 7 by 6 is a simple algorithmic calculation. Estimating the fair price for financial instruments using the Black–Scholes model is a complex algorithmic calculation.

Statistical estimations of the likely election results from opinion polls also involve algorithmic calculations, but provide results made up of ranges of possibilities rather than exact answers.

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*). It also meant a pebble used for calculating, or a small stone used as a counter in an abacus (Latin *abacus*, Greek *abax*). 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.
