What is a pascal calculator made of?

A Pascal calculator, also known as a Pascaline, is typically made of a wooden or metal frame housing a series of interlocking gears and dials. The device features a series of numbered wheels that represent different digits and can perform basic arithmetic operations like addition and subtraction. Its mechanical components are designed to translate manual inputs into calculated results through a system of levers and gears. Overall, its construction combines precision engineering with simple mechanical principles.
