This video tutorial teaches how to solve multiplication problems using the commutative and associative properties. It begins with an introduction to these properties, followed by a review. The tutorial then demonstrates how to apply these properties to simplify multiplication problems, including those involving fractions and decimals. By rearranging and regrouping numbers, the video shows how to make calculations easier and more efficient.

What does the associative property of multiplication state?

• a - b = b - a

• a * b = b * a

• a + b = b + a

• a * (b * c) = (a * b) * c

How can the commutative property help in simplifying multiplication problems?

• By changing the order of subtraction

• By changing the order of multiplication

• By changing the order of addition

• By changing the order of division

When applying the associative property, what is the main action performed?

• Changing the grouping of numbers

• Changing the order of numbers

• Changing the numbers themselves

• Changing the operation from multiplication to addition

What is the benefit of using the commutative property with fractions?

• It makes the fractions larger

• It makes the fractions smaller

• It makes the fractions cancel out

• It makes the fractions more complex

How does the associative property simplify calculations with decimals?

• By changing the decimals to fractions

• By changing the order of decimals

• By changing the grouping of decimals

• By changing the decimals to whole numbers
