You add a delta in any situation where you want to track "how many" of something. (Page views, for example).

I can't immediately imagine when you would want to multiply.

The one I can think of is tuning circuit breakers so that failures are additive but successes decrease more multiplicatively/exponentially, which helps with fast recovery.

That’s more dividing than multiplying though
