Answer
The third and fourth equations are correctly calculated: \( -6 \times -2 = 12 \) and \( -5 \times -5 = 25 \).
Solution
Let's evaluate each of the provided equations to determine which ones are correctly calculated:
1. **\( -18 \div -2 = -9 \)**
- **Calculation:** Dividing two negative numbers results in a positive number.
- **Correct Result:** \( -18 \div -2 = 9 \)
- **Verdict:** **Incorrect**
2. **\( -24 \div 3 = 8 \)**
- **Calculation:** Dividing a negative number by a positive number results in a negative number.
- **Correct Result:** \( -24 \div 3 = -8 \)
- **Verdict:** **Incorrect**
3. **\( -6 \times -2 = 12 \)**
- **Calculation:** Multiplying two negative numbers results in a positive number.
- **Correct Result:** \( -6 \times -2 = 12 \)
- **Verdict:** **Correct**
4. **\( -5 \times -5 = 25 \)**
- **Calculation:** Multiplying two negative numbers results in a positive number.
- **Correct Result:** \( -5 \times -5 = 25 \)
- **Verdict:** **Correct**
**Summary:**
- The **third** and **fourth** equations are **correctly calculated**.
\( -6 \times -2 = 12 \)
\( -5 \times -5 = 25 \)
