What was a drawback of the pascaline calculating device?

A significant drawback of the Pascaline, developed by Blaise Pascal in the 17th century, was its limited functionality. It could only perform addition and subtraction, making it less versatile than later calculating devices. Additionally, the device was prone to mechanical errors and could be cumbersome to use due to its complexity and size. Its reliance on gears also made it difficult to produce and repair, limiting its practicality.
