If the number of negative factors is odd, the sign of the product is negative.If the number of negative factors is even, the sign of the product is positive.

Work Step by Step

If the number of negative factors is odd, the sign of the product is negative.If the number of negative factors is even, the sign of the product is positive. This is shown by the following example: (−2)(−2)=4 (−2)(−2)(−2)=−8 (−2)(−2)(−2)(−2)=16 (−2)(−2)(−2)(−2)(−2)=−32 (−2)(−2)(−2)(−2)(−2)(−2)=64 (−2)(−2)(−2)(−2)(−2)(−2)(−2)=−128 (−2)(−2)(−2)(−2)(−2)(−2)(−2)(−2)=256
