Multiplying Sets of Integers Using the Associative Property on a Number Line

This video tutorial teaches how to multiply sets of integers using the associative property on a number line. It explains the associative property, which states that the product of three or more numbers is the same regardless of grouping. The lesson includes examples of multiplying integers with different groupings, emphasizing that the result remains consistent. The tutorial also addresses common misconceptions, such as the belief that multiplying three negatives results in a positive. By the end, viewers will understand how to apply the associative property to solve multiplication problems involving integers.

What does the associative property of multiplication state?

• The quotient of numbers is the same regardless of grouping.

• The difference of numbers is the same regardless of grouping.

• The sum of numbers is the same regardless of grouping.

• The product of numbers is the same regardless of grouping.

When multiplying 3, -4, and 6, what is the result when grouped as (3 * -4) * 6?

• Positive 72

• Negative 72

• Positive 24

• Negative 24

In the example of multiplying 3, -4, and 6, why do we not flip over the origin when multiplying by 6?

• Because 6 is a prime number

• Because 6 is an even number

• Because 6 is a positive factor

• Because 6 is a negative factor

What is the final result of multiplying -5, -3, and -2 when grouped as (-5 * -3) * -2?

• Negative 15

• Positive 15

• Negative 30

• Positive 30

When multiplying -3 and 2, why do we flip over the origin?

• Because both numbers are positive

• Because one number is negative

• Because one number is positive

• Because both numbers are negative

What is the result of multiplying -3, 2, and 5 when grouped as (-3 * 2) * 5?

• Negative 15

• Positive 15

• Negative 30

• Positive 30

What key concept did you learn in this lesson about multiplying integers?

• Multiplication of integers is always positive.

• The associative property applies to multiplication of integers.

• The associative property does not apply to multiplication of integers.

• Multiplication of integers is always negative.
