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

The stepped reckoner, designed by Gottfried Wilhelm Leibniz, was capable of performing multiplication and division in addition to addition and subtraction, which was beyond the capabilities of Pascal's machine. Leibniz's stepped reckoner utilized a stepped drum mechanism that allowed for more complex mathematical operations to be performed automatically. This advancement in functionality made the stepped reckoner a more versatile and powerful calculating machine compared to Pascal's simpler design.
