Using the Associative Property of Multiplication:
The Associative Property of Multiplication states that changing the grouping of numbers being multiplied does not change the product. This property allows us to rearrange the numbers being multiplied to make the calculation easier.

Step 1: Rewrite the expression
-11 × 1002 can be rewritten as (-1) × 11 × 1002.

Step 2: Apply the Associative Property
Now, we can group the numbers differently:
(-1) × (11 × 1002).

Step 3: Calculate the product
11 × 1002 = 11022.
Now, multiply -1 by 11022:
-1 × 11022 = -11022.
Therefore, -11 × 1002 is equal to -11022 when evaluated using the Associative Property of Multiplication.
This method makes the calculation simpler by breaking it down into smaller, more manageable steps. It showcases how the Associative Property of Multiplication can be utilized to manipulate the order of operations and solve the problem efficiently.
