Let’s solve each problem step by step.
The commutative property of addition means that you can switch the order of the numbers being added, and the sum stays the same. For example:
3 + 4 = 7, and 4 + 3 = 7 — same answer!
So for each problem, we’ll:
1. Add the two numbers to find the sum.
2. Write the same numbers in reverse order (to show the commutative property).
3. Make sure both sides equal the same total.

Problem 1: 7 + 5 = ?
Step 1: 7 + 5 = 12
Step 2: Switch the order → 5 + 7
Step 3: Check: 5 + 7 = 12 → Same!
✔
Answer: 7 + 5 = 12 and 5 + 7 = 12
---
Problem 2: 2 + 4 = ?
Step 1: 2 + 4 = 6
Step 2: Switch the order → 4 + 2
Step 3: Check: 4 + 2 = 6 → Same!
✔
Answer: 2 + 4 = 6 and 4 + 2 = 6
---
Problem 3: 6 + 3 = ?
Step 1: 6 + 3 = 9
Step 2: Switch the order → 3 + 6
Step 3: Check: 3 + 6 = 9 → Same!
✔
Answer: 6 + 3 = 9 and 3 + 6 = 9
---
Problem 4: 7 + 9 = ?
Step 1: 7 + 9 = 16
Step 2: Switch the order → 9 + 7
Step 3: Check: 9 + 7 = 16 → Same!
✔
Answer: 7 + 9 = 16 and 9 + 7 = 16
---
Problem 5: 10 + 0 = ?
Step 1: 10 + 0 = 10
Step 2: Switch the order → 0 + 10
Step 3: Check: 0 + 10 = 10 → Same!
✔
Answer: 10 + 0 = 10 and 0 + 10 = 10
---
Final Answer:
7 + 5 = 12 → 5 + 7 = 12
2 + 4 = 6 → 4 + 2 = 6
6 + 3 = 9 → 3 + 6 = 9
7 + 9 = 16 → 9 + 7 = 16
10 + 0 = 10 → 0 + 10 = 10
