I have noticed that there exists tag, which has at the moment empty tag-wiki and contains two questions:

Is this tag really needed? What was the intended usage of this tag?

Indeed, when searching on internet and in Google Books, it seems that some of the hits are in the context of teaching mathematics. One of the questions that currently have this tag is about creating a mathematical problem.
