The statement "Pascaline can perform addition and subtraction only" is TRUE.

The Pascaline, invented by Blaise Pascal, was primarily designed to perform addition and subtraction directly. While it could perform multiplication and division, it did so through repeated addition or subtraction.

• Addition: The Pascaline used a series of gears to add numbers.
• Subtraction: Subtraction was performed using a complement method.

Therefore, its core functionality was focused on addition and subtraction.
