✔ Step-by-Step Solution

We'll go through each row, complete the Definition and Example, based on standard mathematical properties of real numbers.

---

#### 1. Commutative
- Definition: Order does not matter when adding and multiplying values.
- Example:
$$
3 + 5 = 5 + 3 \quad \text{or} \quad 2 \times 4 = 4 \times 2
$$

---

#### 2. Associative
- Definition: Order doesn't matter when grouping values using addition and multiplication.
- Example:
$$
(2 + 3) + 4 = 2 + (3 + 4) \quad \text{or} \quad (2 \times 3) \times 4 = 2 \times (3 \times 4)
$$

---

#### 3. Additive Identity
- Definition: Adding ____ to any value will not change the value. Identity means ____.
- Completed Definition: Adding 0 to any value will not change the value. Identity means the number that leaves a value unchanged when combined with it.
- Example:
$$
7 + 0 = 7
$$

---

#### 4. Additive Inverse
- Definition: A number which when added to the original number results in zero.
- Example:
$$
5 + (-5) = 0
$$

---

#### 5. Multiplicative Identity
- Definition: Multiplying any value by ____ will not change the value.
- Completed Definition: Multiplying any value by 1 will not change the value.
- Example:
$$
8 \times 1 = 8
$$

---

#### 6. Multiplicative Inverse
- Definition: Multiplying by the ____ of any value will result in the value 1.
- Completed Definition: Multiplying by the reciprocal of any value will result in the value 1.
- Example:
$$
4 \times \frac{1}{4} = 1
$$

---

#### 7. Symmetric
- Definition: The left and right side of an equal sign are the exact same.
- Example:
If $ a = b $, then $ b = a $.
Example:
$$
3 = 5 - 2 \quad \Rightarrow \quad 5 - 2 = 3
$$

---

#### 8. Transitive
- Definition: You can replace one value with an ____ value.
- Completed Definition: You can replace one value with an equal value.
- Example:
If $ a = b $ and $ b = c $, then $ a = c $.
Example:
$$
2 + 3 = 5 \quad \text{and} \quad 5 = 10 - 5 \quad \Rightarrow \quad 2 + 3 = 10 - 5
$$

---

#### 9. Reflexive
- Definition: A value equals ____.
- Completed Definition: A value equals itself.
- Example:
$$
7 = 7 \quad \text{or} \quad x = x
$$

---

#### 10. Distributive
- Definition: Multiply a value by an expression inside parentheses.
- Example:
$$
3(2 + 4) = 3 \times 2 + 3 \times 4 = 6 + 12 = 18
$$
