A syllabus is often considered to be a kind of contract, which the instructor would be violating if they changed the terms without notifying the students. But in the case you're describing it's more likely either you or the instructor made an error in calculating your grade. It's certainly reasonable to ask for an explanation of exactly how your grade was determined.
