The question could be answered in a number of ways:
- Historically (e.g. Egyptians did for <...> reasons)
- Mathematically (It is a highly composite number)
I'm looking for a mathematical answer.
I've got a basic idea of this, but I want to understand any underlying theories, and I want to be more knowledgeable on this matter so as to be able to see similar patterns.
The idea I've used and been told of is:
The ratio of the number of factors of a number to the number itself gives us a good idea of how easily it can be used to count.
The number 12 definitely satisfied this criteria, at least in comparison to many of the numbers that come before it. Hence, there are 12 hours in half a day. It could easily be divided in 4 parts, so that one could do 4 different things, or it could be easily divided into 6 parts... etc.
Please give me further insight.
