The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.

ReneSo, when two negative numbers multiply, their product is a positive number (Remember the rule: minus x minus = plus). So, both the numbers in the factor pair should be either negative or positive to give a positive number as a product. For example: (-3 and -6) and (-2 and -9) form factor pairs for 18.
