The product of two rational numbers is another rational number.

The product of one irrational number and any other number is
irrational, even if the other one is rational.

The product of any two real numbers is never imaginary,
whether either or both of them is rational or irrational.

The product of two numbers is sometimes an integer
and sometimes not an integer.
