Question

which of the following is an example of commutative property of addition ?
8 + 3 = 3 + 8
9 + 7 = 4 + 9
(3 + 6) + 5 = 3 + (6 + 5)
2 x 1 = 2

Explanation:

Step1: Define Commutative Addition

The commutative property of addition states that for any two numbers $a$ and $b$, $a + b = b + a$.

Step2: Evaluate each option

• Option1: $8 + 3 = 3 + 8$ matches $a + b = b + a$.
• Option2: $9 + 7 = 4 + 9$ is false, does not follow the rule.
• Option3: $(3 + 6) + 5 = 3 + (6 + 5)$ is the associative property of addition, not commutative.
• Option4: $2 \times 1 = 2$ involves multiplication, not addition.

Answer:

A. $8 + 3 = 3 + 8$
