Show that the set Z+ × Z+ is countable.
In this problem we need to show that the set is countable.
To show that the countability of a set, we compare the cardinality of this set with a set whose cardinality we already know.
Two sets A and B have same cardinality if and only if there is a one-to-one correspondence from A to B.
