Genesis 5:5 states: "Altogether, Adam lived 930 years . . ."
This number was originally recorded on a clay tablet in sexagesimal numerals as " IIIII ." The sexagesimal number system (with a base of 60) was the first positional number system in the world. It was used throughout the Middle East from about 3000 BC until at least 1700 BC. After that it was slowly phased out in favor of the decimal number system (with a base of 10) that is universally in use today.
During the reigns of the kings David and Solomon (about 1000 BC) learned scribes were commissioned to convert the then long-obsolete sexagesimal numerals to decimal quantities expressed in words.
Could they have erred in their conversions?
This work demonstrates that some very likely and obvious errors were made. It re-examines all the number conversions in the book of Genesis.
