The product of two negative integers is positive. (-a) *(-b) = ab  True

The product of two integers with different signs is positive. (-a) (b) = -ab  False

If two numbers are the same sign, then the product is positive.

a*b = ab   -a * -b = ab   True

The product of a positive and a negative is negative.

-a * b =- ab    a * -b =- ab      True

If the signs of two integers are different, then the product is positive.

-a * b =- ab    a * -b =- ab      False
