Think of  creating a master like going into a print shop and ordering custom-printed stationery.

You tell the printer what you want (designing the master), and he prints it (placing items on master).  Then when you take out a new sheet (create new slide), it already has printed on it all the things you ordered: your name, return address, pretty background, etc. All you have to do is write on it (add slide specific items).
