> Commutative Property of Multiplication:
> For any two numbers `a` and `b`,
> a × b = b × a
This means that changing the order of the factors does not change the product.
Examples:
- 3 × 5 = 5 × 3 → both equal 15
- 7 × 2 = 2 × 7 → both equal 14

#### Question 1:
> A. 7 × 1 = 7
> B. (7 × 2) × 4 = 7 × (2 × 4)
> C. 7 × 2 = 2 × 7 ← ✔ This swaps the order → Commutative
> D. (7 × 2) + (7 × 4) = 7 × (2 + 4)
✔ Answer: C

- Look for equations where two numbers are multiplied in different orders.
- Avoid equations involving addition (distributive), grouping (associative), or multiplying by 1 (identity).
- The commutative property is only about swapping the order of multiplication.

✔ First, let’s understand what the Commutative Property of Multiplication is:
> Commutative Property of Multiplication:
> For any two numbers `a` and `b`,
> a × b = b × a
This means that changing the order of the factors does not change the product.
Examples:
- 3 × 5 = 5 × 3 → both equal 15
- 7 × 2 = 2 × 7 → both equal 14
