If someone told you that the product of two numbers is zero, what could you say about the two numbers? Select all that apply.

If the product of two numbers is zero, the only definitive conclusion is that at least one of the two numbers must be zero. This is due to the multiplication property in mathematics which states that zero multiplied by any number is zero.

Thus, the possibilities for the two numbers could be:

1. One of the numbers is zero and the other is any real number (including zero).
2. Both numbers are zero.

Without additional information, nothing more specific can be determined about the two numbers other than the fact that at least one of them is zero.
