In this system, a person's other hand would count the number of times that 12 was reached on their first hand. They lacked a symbol to serve the function of radix point, so the place of the units had to be inferred from context: could have represented 23 or 2360 or 236060 or 23/60, etc. The Babylonian system is credited as being the first known positional numeral system, in which the value of a particular digit depends both on the digit itself and its position within the number. 1/3 = 0.333), a concept Sumerians could not process at the time. item" : " items" }}.
