Transcript of The Babylonian Number System

The Babylonian Number System Sephora Bergiste May 18, 2011 Ms. Perkins Geometry An inside look into the ancient Babylonian's most outstanding achievement - their number system based on the number "60." This number system started about 5,000 years ago by the Babylonians who lived in ancient Mesopotamia. It was invented to help their people calculate math problems, like we do. However, unlike us, the Babylonians used the number 60 as their base. We've used the number 10 as our base for about four thousand years. Base 60 system = Sexigesimal Base 10 system = Decimal Although their base number was 60, the Babylonians had 59 numbers that fit into the places of the system. This symbol was how they wrote "60". This is how they would write "120". The bigger the number is, the more complicated this system seems to get... For example: 1,57,46,40 would be -
1 x 60^3 + 57 x 60^2 + 46 x 60 + 40 You only understand the problem if you read it from right to left. In decimal form, 1,57,46,40 would equal to 4,240,00. No matter how difficult One thing is for sure: this system may seem to us... IT WORKED FOR THEM! Perhaps one day we might be able to Better understand WHY the Babylonians chose the number "60." And maybe... Just maybe... We might better appreciate it. Work Cited "Babylonian Numerals." Welcome to the Turnbull Server.
