Let's solve each problem by identifying the
multiplication property used in each equation. Here are the common properties of multiplication:
1.
Commutative Property: $ a \times b = b \times a $
→ Order doesn't matter.
2.
Associative Property: $ (a \times b) \times c = a \times (b \times c) $
→ Grouping doesn’t matter.
3.
Identity Property: $ a \times 1 = a $
→ Multiplying by 1 leaves the number unchanged.
4.
Zero Property: $ a \times 0 = 0 $
→ Any number times zero is zero.
5.
Distributive Property: $ (a + b) \times c = (a \times c) + (b \times c) $
→ Multiply a sum by distributing the multiplier.

Now, let’s go through each equation:
---
1. $ 2 \times (5 \times 2) = (2 \times 5) \times 2 $
→ The grouping changes: from $ 2 \times (5 \times 2) $ to $ (2 \times 5) \times 2 $.
✔ Associative Property
---
2. $ 2 \times 7 = 7 \times 2 $
→ The order of numbers is switched.
✔ Commutative Property
---
3. $ 10 \times 1 = 10 $
→ Multiplying by 1 gives the same number.
✔ Identity Property
---
4. $ 2 \times 0 = 0 $
→ Any number times zero is zero.
✔ Zero Property
---
5. $ 4 \times (8 \times 6) = (4 \times 8) \times 6 $
→ The grouping changes: from $ 4 \times (8 \times 6) $ to $ (4 \times 8) \times 6 $.
✔ Associative Property
---
6. $ 4 \times 8 = 8 \times 4 $
→ Numbers are swapped in order.
✔ Commutative Property
---
7. $ (3 + 4) \times 6 = (3 \times 6) + (4 \times 6) $
→ A sum is being multiplied, and it's distributed over addition.
✔ Distributive Property
---
8. $ 5 \times 0 = 0 $
→ Any number times zero is zero.
✔ Zero Property
---
9. $ 11 \times 1 = 11 $
→ Multiplying by 1 gives the original number.
✔ Identity Property
---
10. $ 12 \times (14 \times 11) = (12 \times 14) \times 11 $
→ The grouping changes: from $ 12 \times (14 \times 11) $ to $ (12 \times 14) \times 11 $.
✔ Associative Property
---
11. $ 20 \times 0 = 0 $
→ Any number times zero is zero.
✔ Zero Property
---
12. $ 31 \times 1 = 31 $
→ Multiplying by 1 keeps the number the same.
✔ Identity Property
---
