I decided to categorize this homework as math because it has a lot of math in it despite being assigned by the science teacher.

We categorize the different aspects of our education into different subjects to make them easier to deal with.

Some people like to categorize everything they learn so they can keep the information in their minds more organized.

It will be easier to organize your to do list if you categorize everything that needs to be done and put them in their own group or priority.

I like to categorize my priorities based on how urgent they are, so I know what can be done later and what needs to be done now.
