 Example 1: -2(3)  If there is only one negative it will be a negative answer.  -2(3) = -6

1. -5 * * (8) 4. 9(-4)

 Example 2: -3(-4)  When you multiply a negative by a negative the result will be a positive.  -3(-4) = 12

1. -1 * * * ( -7)

 Example 3: -5(-2)(-3)  When you multiply 3 negative numbers you’ll get a negative answer.  -5(-2)(-3) = -30

 Rule: When you multiply numbers add up the negative signs. If there is an even number the answer will be positive. If there is an odd number the answer will be negative.

1. -1 * -1 * * -3 * (-5)(3) 4. -1(4 * -6)

 Example 4:  When there is only one negative when you divide the answer will be negative.  = -2

 Example 5:  It doesn’t matter if the top or bottom is a negative, the entire fraction is still negative.  Therefore the answer will be negative.  = -3

 Example 6: –  The negative can go with either the top or the bottom number. Either way the answer will be a negative.  – = -5

 Example 7:  When you divide a negative by a negative the result is a positive answer.  =
