    Quick question on set partitions

    I was just wondering if {R+, R-, {0}}, where R is the set of all real numbers, is a partition of R? Thanks!

    You need to show that:
    1)The union between all of them is R. (TRUE. They contain all of the elements.
    2)Any two sets are disjoint. (TRUE).
