Answer 1

Let's solve each problem step by step:

1. **For the equation: 16 + -22 =**
- This can be simplified as \( 16 - 22 = -6 \).
- **Answer: -6**

2. **For the equation: -36 + -10 + 6 =**
- First, calculate \( -36 + -10 = -46 \).
- Then, \( -46 + 6 = -40 \).
- **Answer: -40**

3. **For which subtraction expression has the same difference as -10 - 3?**
- The expression \( -10 - 3 = -13 \).
- We need to find another expression that also equals -13.
- \( -13 - 4 = -17 \) (not equal)
- \( -4 - 13 = -17 \) (not equal)
- \( -4 - 9 = -13 \) (equal)
- \( 4 - 9 = -5 \) (not equal)
- **Answer: -4 - 9**

4. **For the temperature problem: The temperature is 5 degrees at dusk. It is 8 degrees colder at dawn. What is the temperature at dawn?**
- If it is 5 degrees at dusk and it is 8 degrees colder, that can be calculated as \( 5 - 8 = -3 \).
- **Answer: -3**

Here are the summarized answers:
1. -6
2. -40
3. -4 - 9
4. -3
