How do I remove items from the add page screen

Does anyone know of a way to remove all the components on the ‘add new page’ page except for the text box for adding the title name, the content box, and the publish button? I need this page to only contain these parts and am not sure if there is a way to remove the other parts. I have thought about possibly creating a new page that contains this part but am not sure if that would be the best choice. If that is a viable option, does anyone know what the actual page is that does this so I can use it and just remove the parts not needed and modify it as necessary (as a new page because I’m not modifying the core code). This is the last piece I am trying to figure out for the site I am creating and hopefully it will go smoothly.

I just want to thank everyone who has helped me out so far with this endeavor and I look forward to being able to contribute more to this site in the future.

Any help with this would be greatly appreciated. Thank you!
