2. 1.6 Multiplying and
Dividing Integers

3. Multiplying and Dividing two
integers
If the signs are the same, the sign of
the answer is positive.
If the signs are different, the sign of
the answer is negative.

4. True or False ?????
If a product is negative, then there must be
an odd number of negative factors in the
expression.
If a quotient is negative, there must be an
even number of positive factors in the
numerator and denominator combined.
