What about ce que. not sure when to add the 'ce'

Bonjour Judy !

First of all, remember that "ce que" is never used to ASK a question, so no ambiguity there :)
As for the difference of usage between "que" and "ce que" when they introduce a clause in a sentence, here is the link to a lesson which should clarify that point for you:

I hope that's helpful!
