I read once that if you’re trying to get some creativity juices flowing, removing unnecessary details will allow for more abstract thought. Like “write a story about an ogre” would lead to very different stories than “write a story about an ogre doing pushups”, even if the latter is probably arguably more funny.
So that was my thinking here about being a bit vague, I was specifically talking about tankless water heaters which got us on the subject though.
Technically multiplication is just division by the inverse so math has that case covered too
