## cal·cu·lus

(kăl′kyə-ləs) The branch of mathematics that finds the maximum or minimum values of functions by means of differentiation and integration. Calculus can be used to calculate such things as rates of change, the area bounded by curves, and the volume bounded by surfaces. See more at differentiation, integration.

**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**

*Word History**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.*

**calculus**

a branch of mathematics that treats the measurement of changing quantities, determining rates of change (differential calculus) and quantities under changing conditions (integral calculus).
