What is the commutative property of addition

The video tutorial explains the commutative property of addition, which states that A+B equals B+A. It uses real numbers and a number line to demonstrate this property, emphasizing its importance in rearranging expressions and combining like terms. The tutorial highlights the property’s relevance in various mathematical contexts.

What does the commutative property of addition state?

• A + B = B + A

• A + B = A - B

• A + B = A * B

• A + B = A / B

Why is the commutative property important when rearranging expressions?

• It is used to divide terms equally.

• It ensures that the order of addition does not affect the result.

• It allows for the multiplication of terms.

• It helps in changing the operation from addition to subtraction.

Which of the following is an example of the commutative property using numbers?

• 3 + 4 = 7

• 3 + 4 = 3 * 4

• 3 + 4 = 4 + 3

• 3 + 4 = 3 - 4

How does the number line help in understanding the commutative property?

• It shows that subtraction is the same as addition.

• It demonstrates that the order of numbers affects the sum.

• It proves that multiplication is commutative.

• It visually confirms that the sum remains the same regardless of the order.

What is the result of adding 4 + 3 using the number line?

• 9

• 8

• 6

• 7
