Using Property of Multiplication to Evaluate (-7) ×(-9) ×(-11)

To evaluate the expression (-7) × (-9) × (-11), we can make use of the properties of multiplication. One of the properties states that the product of two negative numbers is always positive. Applying this property, we can simplify the given expression as follows:

Step 1: Evaluate (-7) × (-9)
Step 2: Multiply the result from Step 1 by (-11)

Step 1: Evaluate (-7) × (-9)
The product of two negative numbers is always positive. Therefore, the result of (-7) × (-9) will be a positive number.

(-7) × (-9) = 63

Step 2: Multiply the result from Step 1 by (-11)
Since the result from Step 1 is a positive number, multiplying it by another negative number (-11) will result in a negative product.

63 × (-11) = -693

Therefore, (-7) × (-9) × (-11) is equal to -693.

Explanation:
The given expression (-7) × (-9) × (-11) involves the multiplication of three negative numbers. To evaluate this expression, we can use the property that states the product of two negative numbers is always positive. By breaking down the expression into smaller steps, we can simplify it using this property.

In Step 1, we evaluate (-7) × (-9) by multiplying the two negative numbers. Since both numbers are negative, their product will be positive. Therefore, (-7) × (-9) equals 63.

In Step 2, we multiply the result from Step 1 (63) by (-11). Since the result from Step 1 is positive, multiplying it by (-11) will yield a negative product. Thus, 63 × (-11) equals -693.

Therefore, the final result of (-7) × (-9) × (-11) is -693.
