An operator is an instruction to do something to something, e.g. “add the two values on either side of this”, “invert the sign of the value on the right of this” or “divide the value above this by the value below this.”
Punctuation symbols are less direct. “!” signals emphasis, and directs you to raise your volume”. “?” signals a question, and tells you to raise your pitch. “.” indicates the end of an utterance, and is followed by a long pause.
In short, with punctuation, apart from the signalling and speech modification, you don't do anything to anything
