The first scales relied on a simple equal arm device, much like how a seesaw works. However, as scales grew more complex, being able to accurately balance items on both sides of the scale became an important development. By using rocks, weights, and other materials to countervail what was being weighed, merchants could ensure that they were buying and selling the right amount every time.
