If all three numbers are positive then the product obviously has to be positive. If TWO of the three numbers are negative, then the product is also positive. But if exactly ONE of the three numbers is negative or if all THREE are negative, then the product must be negative. In general, a product of numbers is negative if an ODD NUMBER of the terms is negative.

The following rules work for the product of ANY amount of numbers.* If one of the numbers is zero, the product is zero.

* Otherwise, if the number of negative numbers is even (0, 2, 4, 6, etc.), the product is positive.

* Otherwise the product is negative.
