Removing pages

Having challenge with removing pages when i want to create a new document from an old one. In the old adobe acrobat software all i had to do is go to the tools tab and add or remove at the click of a button. The new interface (Windows 10) only shows view pages with no tools option. I only see, find, view modes, print, save as and comment. Am i using a wrong version of this app? The settings do not help either. Please assist. I dont do coding so sending codes will not help.
