3. Copy down
When you multiply or divide integers if the
signs are the same the answer is a positive
If the signs are different than the answer is a
negative.
When You add integers with the same signs
than your answer would be whatever sign it is
when you add integers with different signs then
it would turn into subtraction and the answer
would be the sign of the larger number.
