Pottery Designs from the Tang Dynasty 唐代 618 - 907 AD

The economy was so good in the Tang dynasty that it stimulated interest in developing new ways to account for business other than the abacus. The abacus had clear disadvantages in that it required that you record the answers separately and such scribing could lead to inaccuracies. Thus, paper was invented and roll paper was developed to place in a machine to print the answers once certain numbers were pressed into the machine. It was a great development.
