Mod and remainder are the same thing for positive numbers. The name remainder is more intuitive. With negative numbers its [more confusing](https://stackoverflow.com/questions/13683563/whats-the-difference-between-mod-and-remainder) and you shouldn’t need to deal with that.

Yes that’s correct.

Keep working on the rest. More hints are available.
