This made them cumbersome to carry around, especially when dealing with large quantities or conducting calculations in different locations. Their portability was limited, which hindered their practical use.

2. Time-consuming counting and calculation: Performing counting and calculations using early devices was a time-consuming process. Manipulating physical objects like stones or moving fingers and toes to represent numbers required significant effort and patience. Simple arithmetic operations often took longer to execute compared to modern computational tools.

3. Proneness to mistakes: Early counting devices were prone to human error. Miscounting or misplacement of stones, sticks, or cowries could easily lead to mistakes in calculations. The reliance on manual manipulation increased the risk of inaccuracies, especially when dealing with complex calculations or large numbers.

4. Limited capacity for large numbers: Early counting devices had limitations in representing and manipulating large numbers. Finger counting, for example, was limited to numbers within the range of 20. Using physical objects like stones or cowries also imposed practical limits on the quantity they could represent. Dealing with calculations involving significant numerical values was challenging or impossible with these devices.

5. Difficulty in remembering results: Unlike modern digital devices that can store and recall calculations easily, early counting devices lacked built-in memory or storage capabilities. When performing complex calculations, remembering interim results or carrying forward calculations required mental effort. This increased the likelihood of forgetting or making errors in subsequent steps.

6. Lack of storage facilities: Early counting devices lacked proper storage facilities, making it difficult to preserve and retrieve previous calculations or counts. Storing and organizing large amounts of data or information was impractical or impossible with these devices. This posed challenges for record-keeping, historical analysis, and referencing past calculations.

While early counting devices served as fundamental tools for basic arithmetic, their limitations became apparent as human societies advanced and encountered more complex numerical challenges. The development of more advanced computational devices overcame these disadvantages by offering improved portability, speed, accuracy, memory capacity, and storage capabilities.
