`{16-(4 + 18 divide 6 - bar(7-5)) xx 5]`

Explanation

To solve the expression `{16 - (4 + 18 ÷ 6 - bar(7 - 5)) × 5}`, we will follow the order of operations known as BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Evaluate the expression inside the brackets**:
- Start with `7 - 5`.
- Calculation: `7 - 5 = 2`.
- Now, substitute this back into the expression:
\[ 16 - (4 + 18 ÷ 6 - 2) × 5 \]

2. **Perform the division inside the brackets**:
- Now calculate `18 ÷ 6`.
- Calculation: `18 ÷ 6 = 3`.
- Substitute this back into the expression:
\[ 16 - (4 + 3 - 2) × 5 \]

3. **Complete the operations inside the brackets**:
- Now, calculate `4 + 3 - 2`.
- Calculation: `4 + 3 = 7`, then `7 - 2 = 5`.
- Substitute this back into the expression:
\[ 16 - (5) × 5 \]

4. **Perform the multiplication**:
- Now calculate `(5) × 5`.
- Calculation: `5 × 5 = 25`.
- Substitute this back into the expression:
\[ 16 - 25 \]

5. **Perform the final subtraction**:
- Now calculate `16 - 25`.
- Calculation: `16 - 25 = -9`.

### Final Answer:
The value of the expression is `-9`.
