At this level, you have gotten to know the double type and learned what operations can be performed on it. You also learned how to work with data input.

To consolidate your knowledge, you need to solve tasks, of course. And a bit of "reading at home" won't hurt either. Here are some lessons to help you delve deeper into the topics we covered.
