Hi, friends!!! Please read this following sentence: [color=blue] “She’s a zillion times brainier than I am.”
How to use “times+adj(-er) than …” in the comparative degree form? Can I say [color=blue]“She 's zillion times brainier than me?”
Yes, that’s right. Using “than me” is a very normal, typical and widely used conversational style. Your sentence seems to be just right for it ;). If you want to be more formal, use your first sentence: “than I am.”
Saying “than I” (in other words, without “am”) would be extremely formal.
