  2. A particular method or system of calculation or reasoning

  3. A concretion of minerals formed within the body, esp. in the kidney or gallbladder

  1. (calculus) a hard lump produced by the concretion of mineral salts; found in hollow organs or ducts of the body; "renal calculi can be very painful"
  2. (calculus) tartar: an incrustation that forms on the teeth and gums
  3. (calculus) the branch of mathematics that is concerned with limits and with the differentiation and integration of functions
  4. Calculus (Latin, ', a small stone used for counting) is a branch in mathematics focused on limits, functions, derivatives, integrals, and infinite series. This subject constitutes a major part of modern mathematics education. ...
  5. (Calculus (book)) Michael David Spivak (born 1940 in Queens, New York) is a mathematician specializing in differential geometry, an expositor of mathematics, and the founder of Publish-or-Perish Press. He is the author of the five-volume Comprehensive Introduction to Differential Geometry. ...
  6. (Calculus (dental)) In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by the continual accumulation of minerals from saliva on plaque on the teeth. Its rough surface provides an ideal medium for further plaque formation, threatening the health of the gingiva.
  7. (The calculus) Infinitesimal calculus was independently developed by both Leibniz and Newton in the 1660s, drawing on the work of such mathematicians as Barrow and Descartes. ...
  8. (calculus) calculation, computation; Any formal system in which symbolic expressions are manipulated according to fixed rules; Differential calculus and integral calculus considered as a single subject; analysis; A stony concretion that forms in a bodily organ; Deposits of calcium phosphate ...
  9. (Calculus) Hard residue, commonly known as "tarter," that forms on teeth due to inadequate plaque control, often stained yellow or brown.
  10. (Calculus) Same as tartar.  Occurs when plaque is left on the teeth untreated.   A hard substance that acts an irritant by wedging between the tooth and gum.   Left untreated calculus can eventually lead to periodontal disease.
  11. (CALCULUS) The sticky film on your teeth (plaque) that has hardened. Also known as tartar.
  12. (Calculus) a sticky substance, also called Tartar, that has hardened.
  13. Calculus refers to any abnormal stony mass or deposit formed within the body, usually composed of mineral salts.
  14. (Calculus) hardened deposit of mineral salts formed around the teeth.
  15. (Calculus) The scientific term for tartar, which is a hard deposit that typically forms due to poor oral hygiene. When plaque mineralizes and hardens it forms calculus.
  16. (Calculus) Another word for calcified plaque or hard tartar deposits on teeth.
  17. (Calculus) Also called tartar. A tenacious, hardened material formed by mineralization (calcification) of dental plaque, which once formed can only be removed by a dentist/hygienist.
  18. (calculus) Hard deposit of mineralized material adhering to crowns and/or roots of teeth.
  19. (Calculus) Hard, yellow-brown mineralised deposits on tooth surfaces. Also called Tartar.
  20. (Calculus) also known as "tartar", this hardened plaque clings on to teeth, eventually leading to tooth decay and gingivitis. Tartar buildup is hard to remove by ordinary means and may require dental products and apparati to clean.
  21. (CALCULUS) Any type of hard concretion (stone) in the body, but usually found in the gallbladder, pancreas, and kidneys. They are formed by the accumulation of excess mineral salts and other organic material such as blood or mucous. Calculi (pl. ...
  22. (CALCULUS) hard calcium like deposits which form on teeth and dentures.
  23. (Calculus (& Computers)) This is a major theme of my research.
  24. (Calculus) (Also called tartar.) Calcified plaque that forms from mineral salts in the saliva and deposits on the teeth. Removed in the course of a prophylaxis, or dental cleaning. ...
  25. (Calculus) A stone, usually in the kidney or ureter, but may also occur in the prostate or bladder
