I'm on #7, and I don't really grasp the idea of or. Can somebody please help?
I'm not sure what you mean by the idea of or, so let me tell you how I see it
OR gives FALSE only when all conditions are false, in any other case it gives TRUE.
For example if we have
this will return true, because 3 is bigger than 2.
3>2 or 1>5
Does it make anything easier? If not then tell me, preferably on example what makes you a problem.
