What does the stepped reckoner do that pacals machine couldn't?

The Stepped Reckoner, developed by Gottfried Wilhelm Leibniz, was capable of performing all four basic arithmetic operations: addition, subtraction, multiplication, and division, which was a significant advancement over Pascal's machine, the Pascaline. While Pascal's machine could only add and subtract, the Stepped Reckoner employed a unique stepped drum mechanism that allowed for more complex calculations. This made it a more versatile tool for mathematical computation compared to Pascal's earlier invention.
