Synonyms: See Also: Webster's 1913 Dictionary Definition: ```\Cal"cu*lus\, n.; pl. {Calculi}. [L, calculus. See {Calculate}, and {Calcule}.] 1. (Med.)

(Math.) A method of computation; any process of reasoning by the use of symbols; any branch of mathematics that may involve calculation. {Barycentric calculus}, a method of treating geometry by defining a point as the center of gravity of certain other points to which co["e]fficients or weights are ascribed. {Calculus of functions}, that branch of mathematics which treats of the forms of functions that shall satisfy given conditions. {Calculus of operations}, that branch of mathematical logic that treats of all operations that satisfy given conditions. {Calculus of probabilities}, the science that treats of the computation of the probabilities of events, or the application of numbers to chance. {Calculus of variations}, a branch of mathematics in which the laws of dependence which bind the variable quantities together are themselves subject to change. {Differential calculus}, a method of investigating mathematical questions by using the ratio of certain indefinitely small quantities called differentials. The problems are primarily of this form: to find how the change in some variable quantity alters at each instant the value of a quantity dependent upon it. {Exponential calculus}, that part of algebra which treats of exponents. {Imaginary calculus}, a method of investigating the relations of real or imaginary quantities by the use of the imaginary symbols and quantities of algebra. {Integral calculus}, a method which in the reverse of the differential, the primary object of which is to learn from the known ratio of the indefinitely small changes of two or more magnitudes, the relation of the magnitudes themselves, or, in other words, from having the differential of an algebraic expression to find the expression itself. ``` Medical Dictionary Definition: Accumulation of mineral salts in various parts of the body, such as a kidney stone or on teeth. Biology Dictionary Definition: A calculus is a mineral deposit resembling a stone at abnormal body locations. Plural: calculi. A kidney stone is called a renal calculus; stones in the salivary glands are called calculi of the salivary glands. The clinical condition of having calculi, however, is described by (medical name of organ)-lithiasis. For example: the condition of kidney stone: nephrolithiasis gallbladder stone: cholelithiasis stone in salivary glands: sialolithiasis
