Terms and Concepts (A)

The Product of two integers with different signs is negative Ex. 3(-2) = -6

The Product of two negative integers in positive Proof:

0 = -2 (0) 0 = -2 ([3 + -3]) (substitute a zero pair) 0 = -2(3) + -2(-3) (distribution prop.) 0 = -6 + 6 (the product has to be positive to make the

expression true.
