Hmm.. trying to think about how I would use it. I suppose it makes sense to have a item class and then use inheritance with it. Trying to think about how it would fit in the 3 pillars I started with: input, calculator, print.

Right now you have computational classes - models that are intended to do something - but there are other types of models, too. For example, in a standard Rails model, an Item would be a standard model, right? You can use it just like a Rails model (minus persisting to the db).

Actually, now that I'm thinking about it, you might be able to rearchitect around Items and Lists, which would have Calculate, Print, and Input as modules or methods. I think modeling around computation isn't that common.
