    Using what I learned about the Roster and set-builder notation for sets, I want to make-up my own examples. Let me know if I am correct or not.

    Let Z = the set of all y greater than 0.

    Roster Method

    Z = {0, 1, 2, 3, 4, 5, . . . }

    Yes?

    Set-Builder Notation Method

    Z = { y| y > 0 }

    Yes?

    all y greater than 0 means 0 is excluded

    Z = {1, 2, 3, 4, 5, . . . }

    Yes, true. I know that y > 0 means DO NOT INCLUDE ZERO.
