As you can see, this topic is (or was) under 3rd, 4th, 5th, 6th, 7th and 8th grade math missions. Therefore there is one category for each of these math missions so that you can count the exercises by going to this category. This particular exercise has been removed from 8h grade, which is why it is in the recently edited list right now.

Additionally, in each mission the category is under a certain subtopic which connects it to a challenge patch with in the category. Each challenge patch also counts the number of topics needed to earn it as can be seen here. I also include mission foundations if that is the subtopic, even though this does not have a challenge patch associated with it.

You can see the discussion of what I have been doing with regards to exercises and the categories on the exercise pages in my blog which I have been updating regularly here. I have been posting updates as I discover new things and as I reach certain milestones.
