# Do we delete some of the questions that have been closed?

There are at least seven pages of closed questions (I got the list by searching for closed:1 the).

Some of them are clearly off-topic and I believe we can delete them.

Here are a few:

https://math.stackexchange.com/questions/3045/how-do-i-write-math-equations-for-my-proffesor-closed

https://math.stackexchange.com/questions/3482/inserting-chapters-into-a-latex-document-closed

https://math.stackexchange.com/questions/4118/is-it-possible-to-apply-brightness-and-contrast-on-an-image-using-raster-operatio

https://math.stackexchange.com/questions/4940/3d-modeling-vertex-resolution-closed

I believe we can also delete the ones closed as "Not a Real Question".
