    Difference between kleene star and a plus

    Homework Statement So this isn't a question from a homework directly, but it's been used in my textbook an I'm not sure of the difference. For example, if I have a* and a+, what is the difference Homework Equations The exact wording in the book was {0,1}* and {0,1}+ The Attempt at a Solution...

    Solving Discrete Math Question: Proving ∪n=2∞[0,1 - 1/n] = [0,1)

    Okay so I did this, ∪n=2∞[0,1 - 1/n] = [0,1/2), [0,2/3), [0,3/4),...,[0,n-1/n). Since n-1/n < 1, by union properties ∪n=2∞[0,1 - 1/n] = [0,1). Would this suffice?

    Solving Discrete Math Question: Proving ∪n=2∞[0,1 - 1/n] = [0,1)

    My method was to first show that when n = 2 the answer was [0,1). Then I had an arbitrary integer greater than 0, such that ∪n=2∞[0,1-1/(k+2)) = [0,1). Would this be sufficient?
