CFrame:Inverse not working as intended?

Alright, I just searched and found this answer:

You might have to have some knowledge of matrices to understand everything this is saying. If you don’t understand matrices you can try learning about them here.

Because CFrames are really just inverses, I’m guessing that that the inverse is the same as the Inverse of a Matrix.

Honestly, I completely forgot that CFrames were matrices. That’s my bad. You can try checking out the resources below.

It might take you awhile to understand if this is all new to you. Instead, can you tell me what exactly you are trying to accomplish by using the inverse?
