calculating

adj. careful, shrewd

v. estimate; compute (add, subtract, etc.); depend upon

A calculation is a deliberate process for transforming one or more inputs into one or more results. 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.Multiplying 7 by 8 is a simple algorithmic calculation.
