  1. An instrument for performing multiplication and division. The multiplicand is made to appear in one place by setting certain stops or wheels. A handle is then turned, and other motions are made, so as to cause the multiplier to appear in another place. Then the product will be found in a third place. Division and subtraction can be performed in a somewhat similar way. The best-known of these machines is by Thomas of Colmar; the best is by Grant.
