< /ˈkæl kyəˌlaɪ/, cal·cu·lus·es.

  1. Mathematics. a method of calculation, especially one of several highly systematic methods of treating problems by a special system of algebraic notations, as differential or integral calculus.
  2. Pathology. a stone, or concretion, formed in the gallbladder, kidneys, or other parts of the body.
  3. Also called tartar. Dentistry. a hard, yellowish to brownish-black deposit on teeth formed largely through the mineralization of dead bacteria in dental plaques by the calcium salts in salivary secretions and subgingival transudates.
  4. calculation; estimation or computation: the calculus of political appeal.

noun plural -luses

  1. a branch of mathematics, developed independently by Newton and Leibniz. Both differential calculus and integral calculus are concerned with the effect on a function of an infinitesimal change in the independent variable as it tends to zero
  2. any mathematical system of calculation involving the use of symbols
  3. logic an uninterpreted formal systemCompare formal language (def. 2)
  4. plural -li (-ˌlaɪ) pathol a stonelike concretion of minerals and salts found in ducts or hollow organs of the body

1660s, from Latin calculus “reckoning, account,” originally “pebble used as a reckoning counter,” diminutive of calx (genitive calcis) “limestone” (see chalk (n.)).
