Let’s go through each problem one by one. We’re looking for the property that makes the two sides of the equation equal — meaning, why is it okay to rewrite the expression this way?

Problem 1:
(1 + 3) + 9 = 1 + (3 + 9)
This shows grouping changing in addition — but the order of numbers stays the same. That’s the
Associative Property of Addition.
✔ Correct answer:
Associative Property of Addition
---
Problem 2:
(5 + 8) + 7 = 5 + (8 + 7)
Same as above — parentheses move, but it’s still all addition and same numbers. Again,
Associative Property of Addition.
✔ Correct answer:
Associative Property of Addition
---
Problem 3:
(7 + 3) + 2 = 7 + (3 + 2)
Again, just regrouping addends — no change in order. Still
Associative Property of Addition.
✔ Correct answer:
Associative Property of Addition
---
Problem 4:
(6 + 9) + 2 = 6 + (9 + 2)
Same pattern — moving parentheses around in an addition problem. Still
Associative Property of Addition.
✔ Correct answer:
Associative Property of Addition
---
Problem 5:
6 + 2 = 2 + 6
Here, the order of the numbers changed — not the grouping. This is swapping places → that’s the
Commutative Property of Addition.
✔ Correct answer:
Commutative Property of Addition
---
Problem 6:
(5 · 3) · 9 = 5 · (3 · 9)
Now we have multiplication (the dot “·” means multiply). The grouping changes, but order stays same → that’s
Associative Property of Multiplication.
✔ Correct answer:
Associative Property of Multiplication
---
Final Answer:
1. Associative Property of Addition
2. Associative Property of Addition
3. Associative Property of Addition
4. Associative Property of Addition
5. Commutative Property of Addition
6. Associative Property of Multiplication
