Find the value of :
`11-9+5-6-3+7`

Answer

To find the value of the expression \( 11 - 9 + 5 - 6 - 3 + 7 \), we can follow these steps:

### Step-by-Step Solution:

1. **Write down the expression**:
\[ 11 - 9 + 5 - 6 - 3 + 7 \]

2. **Group the positive and negative numbers**:
- Positive numbers: \( 11, 5, 7 \)
- Negative numbers: \( -9, -6, -3 \)

3. **Calculate the sum of the positive numbers**:
\[ 11 + 5 + 7 \]
- First, add \( 11 + 5 = 16 \)
- Then, add \( 16 + 7 = 23 \)
- So, the sum of positive numbers is \( 23 \).

4. **Calculate the sum of the negative numbers**:
\[ - (9 + 6 + 3) \]
- First, add \( 9 + 6 = 15 \)
- Then, add \( 15 + 3 = 18 \)
- So, the sum of negative numbers is \( -18 \).

5. **Combine the results of the positive and negative sums**:
\[ 23 - 18 \]
- Subtract \( 18 \) from \( 23 \):
\[ 23 - 18 = 5 \]

6. **Final result**:
The value of the expression \( 11 - 9 + 5 - 6 - 3 + 7 \) is \( 5 \).
