This is music friend, its not mathematics so don't multiply. Just count all the notes like a nursery school kid. d r m f s l t d' r' m' f' s' l' t' d''. Now how many notes are those?

One C to the next is 8. That C to the next C is 8. Together, they're 15, because you don't count the C in the middle twice.

It takes 8 notes to get from one C to the next C but only 7 more to get to the following C. It works the same no matter what note you begin on.

It just is. It's an interval of a 15th. If you don't believe it count inclusively the number of notes from one C on the piano to a C two octaves above. If you're curious, three octaves up would be 22va though I've never seen it written down
