This is called zero property of whole numbers. *Subracting negative numbers is the same as adding positive numbers �

Multiplying positive and negative numbers �There is four cases for multiplication: �Pos x pos =pos �Neg x neg = neg �Neg x pos = neg �Pos x neg = neg �

Dividing positive and negative numbers �Ther is four cases in division �Pos x pos =pos �Neg x neg = neg �Neg x pos = neg �Pos x neg = neg �
