Answer 1

Answer:

The mill was the calculating unit in the anlytical engine​

Explanation:

An arithmetic unit (the "mill") would be able to perform all four arithmetic operations, plus comparisons and optionally square roots. Initially (1838) it was conceived as a difference engine curved back upon itself, in a generally circular layout, with the long store exiting off to one side.
