It teaches about shadowing, which is not really useful if used like this (nor is it appropriate at this point in the curriculum).

At the very least I'd suggest elaborating on what's expected. Of course the hint has it, but for those who don't want to go for hints 🙂 it would be helpful to clarify that what the exercise wants is to preserve the println! lines as-is too, i.e., to have that number + 2 piece intact.
