The theory that I am attempting to formulate is being complicated by the intrusion of ancient Greeks into the mix. Their number system is decimal in nature (probably lacking zero). My question is this.

 

How old would a decimal Greek number system be likely to be? Could it be older for instance than the Arabic Islamic system which, by definition, must be newer than 500AD I always believed that the Muslims invented the decimal system. A date would be useful.
