The instructions for this are horrible. At first it says that you need to print out numbers from 0 - 35, incrementing by 5 each time. Then it says you go to 50. Why bother putting 0 - 35? Why not just put 0 - 50?
As far as I remember the 0 to 35 is default and your task is to fix this range to 0 to 50, right? If not it would probably make it easier if you copy paste the task or link to the exercise you're referring to.
