Abstract

The arithmometer is peculiarly adapted for working out the
chief details of a classified valuation of a life assurance office.
The process is a simple one, being merely a series of multiplications,
and the work can be carried out very rapidly by an
ordinary computer. The results worked out and set down by
one computer can be checked and verified by a second computer
using a different machine, while any errors in the
original work may be investigated by a third worker, using a
third machine. By this means complete accuracy is ensured,
and the use of the different machines avoids any possibility of
error should either of them happen to fall out of order and
become liable to repeat its own mistakes.
It is usual to describe the arithmometer as a
machine which enables a person, however unskilled himself,
to perform the operations of multiplication and division with
facility, rapidity, and unfailing accuracy. This, as a description,
is correct as far as it goes, but as an enumeration of the
properties of the machine it is inadequate and defective. It
entirely omits that property which forms its special adaptation
to our purpose, and in default of which its utility would
be comparatively limited. Besides the facilitation of the
operations named the machine will also in forming the product
of two given numbers either add that product to or subtract
it from another given number according to the pleasure of the
operator
