What is a "calculating machine"?
A calculating machine is a mechanical device used to perform arithmetic operations like addition, subtraction, multiplication, and division. It typically operates by turning knobs, pressing buttons, or cranking levers to input numbers and functions. The machine then uses gears or other mechanical parts to carry out the calculations. Early calculating machines were used in offices, banks, and businesses to speed up manual calculations, and they played an important role in the development of modern computers. While most calculating machines are no longer used, they laid the foundation for today's digital calculators.
Example
The vintage calculating machine displayed in the museum was a marvel of engineering from the early 20th century.
My grandfather still keeps his old calculating machine in the attic, a relic from his days as an accountant.
