n., pl. -li (-ˌlaɪ)
1. a method of calculation, esp. one of several highly systematic methods of treating problems by a special system of algebraic notations, as differential or integral calculus.
2. a stone, or concretion, formed in the gallbladder, kidney, or other part of the body.
3. a hard, yellowish to brownish black deposit on teeth formed largely through the calcification of dental plaque; tartar.
4. calculation: the calculus of political appeal.

Word History The branch of mathematics called calculus deals with problems that simple arithmetic or algebra cannot deal with, such as finding areas and volumes of unusual shapes and solids, and measuring rates of change. The word calculus comes from the Latin word that means "little stone, pebble." How did a word meaning "little stone" come to refer to this branch of mathematics? The answer comes from the counting practices of the ancient Romans over 2,000 years ago. They would add things up by using little pebbles or stones that represented particular numbers, as on an abacus. Later, the word calculus came to mean not just the pebble used in counting, but a counting system itself. Much more recently, it came to refer to the modern branch of mathematics, which was invented in the 17th century. The word calculus, incidentally, is also the source of the Latin word calculare, "to add up," which gives us our word calculate.
a branch of mathematics that treats the measurement of changing quantities, determining rates of change (differential calculus) and quantities under changing conditions (integral calculus).See also: Mathematics
