I don't understand D.R.Y


I don't understand. Plz help.


Replace this line with your code.


Go back to lesson 1 and do a complete review, including re-reading the lesson text for each lesson. Study the exercises you have completed so far, and check them against the instructions. Let you mind juggle the concepts and reason through to manually check your work. By the time you get back to Lesson 6 you won't have this question.
