Understanding the Commutative Law of Multiplication

The video tutorial explains the commutative law of multiplication, which states that the order of factors does not affect the product. It demonstrates this concept using the example of 2 times 34 and 34 times 2, showing that both yield the same result, 68. The tutorial emphasizes that the commutative property allows flexibility in the order of multiplication, making calculations easier.

What does the commutative law of multiplication state?

• Division is the opposite of multiplication.

• Multiplication is always greater than addition.

• The order of multiplication does not matter.

• The order of addition matters.

How can you express 2 times 34 using the commutative law?

• 34 times 34 is the same.

• 2 times 34 cannot be changed.

• 2 times 34 is the only way.

• 34 times 2 is another way.

What is the result of 2 times 34?

• 64

• 66

• 68

• 70

When simplifying 2 times 34, what is the first step?

• Subtract 2 from 34.

• Add 4 and 2.

• Multiply 3 by 2.

• Multiply 4 by 2.

What is the result of 34 times 2?

• 68

• 64

• 70

• 66

Why is it often easier to write the number with more digits on top?

• It is a tradition.

• It is a rule of mathematics.

• It makes the calculation faster.

• It helps in organizing the calculation.

What does the commutative law demonstrate with 34 times 2?

• The result is always negative.

• The result is always zero.

• The result is the same as 2 times 34.

• The result is different from 2 times 34.
