What is the identity property of multiplication

The video tutorial explains the identity property of multiplication, which states that any real number multiplied by one remains unchanged. This property is crucial for solving equations as it allows for the isolation of variables. The commutative property is also mentioned, highlighting that the order of multiplication does not affect the result. Understanding these properties is essential for simplifying mathematical expressions and solving equations effectively.

What is the identity property of multiplication?

• A number multiplied by zero equals zero.

• A number multiplied by one equals the number itself.

• A number multiplied by itself equals one.

• A number multiplied by two equals double the number.

Which number is considered the identity element in multiplication?

• Zero

• One

• Two

• Ten

How does the commutative property relate to the identity property of multiplication?

• It states that the order of multiplication does not matter.

• It states that division by one is the number itself.

• It states that the order of addition does not matter.

• It states that multiplication by zero is always zero.

Why is the identity property important in solving equations?

• It is used to multiply large numbers.

• It simplifies division.

• It is used to isolate variables.

• It helps in adding numbers.

What happens when you multiply any number by one?

• The number becomes negative.

• The number doubles.

• The number becomes zero.

• The number remains unchanged.
