Описание:
One of the important contributions of the Sumerians were the number system based on 60 (basis for 60 minutes in an hour and 360 degrees in a circle), the first wheeled vehicles, and the first formal school known as the edubba. All of these were important for the development of human civilization.Celada, A., & Dela Cruz, E.(2019)
