Did a pascal machine make use of mechanical gears?

Yes, the Pascaline, invented by Blaise Pascal in the 17th century, utilized mechanical gears as part of its design. This early mechanical calculator employed a series of interlocking gears to perform addition and subtraction by manipulating the position of the gears based on the input numbers. The use of gears allowed for the representation and calculation of numerical values, marking a significant advancement in computing technology at the time.
