MULTIPLYING RATIONAL NUMBERS LESSON 8 Multiplying Integers Positive x Positive = Positive Positive x Negative = Negative Negative x Negative = Positive Negative x Positive = Negative An odd number of Negatives multiplied together gives a negative result. An even number of Negatives multiplied together gives a positive result.

REMEMBER: If there are negative signs to place them in the numerator.
