A calculating machine is a device used to perform the basic operations of arithmetic. One noted machine was the Victorian British scientist Charles Babbage's Difference Engine (No. 2), designed in the 1840s but never completed in the inventor's lifetime. A working example, based on Babbage's original specifications and using only materials available during the mid-19th century, was built at the London Science Museum in the late 1990s.
