If m is countable, it means that there exists a one-to-one correspondence between the set of natural numbers and the set of elements in m.

Since there is a one-to-one correspondence between the elements of m and the natural numbers, we can create a similar one-to-one correspondence between the elements of m x m and the natural numbers, making m x m countable. **
