The invention of arithmetics

The video is about the invention of arithmetics . It was represented as a token. With tokens you can add and take away. The reasons why the Sumerians needed arithmetics: there were so many people living in  the same place, cities need organizing, grain had to be stored and distributed, working out how much each person should get required arithmetic. With tokens, people could assess the profits, calculate the wealth and the loss and to finish collect the taxes.
