Multiplying and Dividing Integers

Use the following rules for multiplying and dividing integers:

-  (negative) × (negative) = positive
-  (negative) ÷ (negative) = positive
-  (negative) × (positive) = negative
-  (negative) ÷ (positive) = negative
-  (positive) × (positive) = positive
-  (positive) ÷ (negative) = negative

Examples:
Example 1.  Solve.
Solution: Use this rule: (positive) × (negative) = negative.
Then:

Example 2.  Solve.
Solution: First, divide by , the numbers in brackets, use this rule:
(negative) ÷ (positive) = negative. Then:


Example 3.  Solve.
Solution: First, subtract the numbers in brackets,

Now use this rule: (negative) (negative) = positive

Example 4.  Solve.
Solution: First, subtract the numbers in brackets,

Now use this rule: (positive) (negative) = negative
