### Why 360?

Sunday, October 4, 2009
Do you know why 360 degrees is a full circle? The reason why we use the number 360 is because it started with the Babylonians.

Now in the present, we use the base of 10, when once in the past, the Babylonians used the base of 60. That system that they used was called the Sexogonal System. The Babylonian also made a calendar that had 360 days because they believed that the earth has a full rotation after every 360 days.

Also, if you haven't noticed, 360 is a very handy number. It can be divided by alot of numbers. It has alot of factors such as: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360.

I hope you guys learnt something number about why we use the number 360. Please comment if you would like to add something to my post (:

Good job Melissa! Very understandable and great pictures. But in my opinion, you should use font colours that stand out more, so you could get the message out more. But overall, great work (;
