Everything you need to know about Accounting Machines


1. Calculating Machine

Calculating machine replaces the human labour in operations of adding, subtracting, multiplying and dividing of arithmetical figures. To err is human. Mistakes may occur, when dealing with figures. The chances of these mistakes are completely removed by the calculating machines. These machines are also used for calculation including interest, commission, discount, exchange, etc. These machines can perform four or five times the work done by a man.

2. Adding-listing Machine


Simple adding machines will show the result of adding operation, whereas adding- listing machine will give a printed record in the adding operation. There are three kinds-full rank type, half keyboard type and simplified keyboard. In non-listing machines, the result appears in the metre and it will not give printed answers.

In all types, the figures of the keyboard are pressed and the result is known then a particular key is pressed to clear off the metre.

The following are the general types:

1. Printing calculators


2. Key-driven calculators

3. Automatic calculators

4. Rotary calculators

5. Electronic calculators


6. Electronic printing calculators etc.

Printing calculator is like an adding machine which gives the result in printed form.

Key-driven calculator is a non-listing machine, which gives the result on the metre. Automatic calculator is run electrically and gives the result on the metre.

Rotary calculator is a machine which does all the functions of arithmetic.


Electronic calculator is the latest development. This machine will perform calculations in a thousand part of a second and some machines will display the result on a small screen, as in a television set. Electronic printing machine in addition to the above, will also give printed result.
