Did You Know?

In Latin calculus meant “pebble.” Because the Romans used pebbles to do addition and subtraction on a counting board, the word became associated with computation. Other English derivatives include calculator and calculation. Calculus itself has been borrowed into English as a medical term that refers to masses of matter in the body such as kidney stones (a straightforward extension of the meaning “pebble”) and to refer to a system of mathematical computation.
