Classification and Division. What it actully means.

I don’t know about you, but when I hear classification and division, I think of math, or recently, of English. In both cases, it makes me yawn and want to sleep. So, without using those exact words, what does it actually mean?

In my words, it is the process of pulling out certain points in a story. Take schooling for example. It can be classified as going to a school building to learn and increase your intelligence. If you want to divide it, I would divide it into elementary school, junior high, high school, and college.  You can further divide it into what subjects were studied in what years, what periods you had what class, and so on. To break a subject down into smaller parts and looking at those smaller parts separately, as well as combined into a group such as schooling.
