Early counting devices (Definition and Examples)

Early counting devices are devices that were used in the early days to perform arithmetic operations such as addition of numbers, subtraction and multiplication. These devices were used for the usual barter trade of the early days.

Examples of early counting devices are fingers, toes, stones, sticks, pebbles, cowries among others.

The history and development of computer can be traced back to the studies of Mathematics which started with counting. The history of Mathematics is the history of civilization.

These has led to various computing inventions in search for a tool that could enable man meet his computational and data processing needs until we have the computer today.

As time went on, fingers and toes method became ineffective, especially for large numbers, hence, the emergence of counting and solving basic arithmetic problems with the use of stones and sticks.

Limitations to the Early Counting Devices

The problems posted by these early counting and data processing method were enormous.

1. They could not be used for counting large numbers efficiently.
2. It is stressful
3. It required man power
4. It is time consuming
5. It requires more of that device to perform a large number of counting
