did we learn this in the previous lesson?..

The "sum method" hasn't been taught yet. You don't have to complete this task to move forward. I'm sure it will be covered in a future lesson. Sometimes more difficult tasks are provided even if the solutions haven't been presented yet. This is why they offer greater amounts of dark matter.

We, as Java developers, don't necessarily have to learn something before practicing but the total opposite. Have a glass of wine/orange juice, or do whatever else to relax you and try to read/understand the code that is displayed to you. You'll learn so fast just practicing and figuring how everything works! 👍 Try everything that is in your mind to find the solution even you know you are wrong. Small step by small step, you'll find it sooner than you expected.
