Which of the following is different from the others?

Options

A. 20 + ( –25)
B. (– 37) – (– 32)
C. `(-5)xx(-1)`
D. `(45)-:(-9)`

Answer

To solve the question "Which of the following is different from the others?" we will evaluate each option step by step.

### Step 1: Evaluate Option 1
Option 1 is \(20 - 25\).
- Calculation:
\[ 20 - 25 = -5 \]
- Result: The value of Option 1 is \(-5\).

### Step 2: Evaluate Option 2
Option 2 is \(-37 - (-32)\).
- Simplifying the expression:
\[ -37 - (-32) = -37 + 32 \]
- Calculation:
\[ -37 + 32 = -5 \]
- Result: The value of Option 2 is \(-5\).

### Step 3: Evaluate Option 3
Option 3 is \(-5 \times -1\).
- Calculation:
\[ -5 \times -1 = 5 \]
- Result: The value of Option 3 is \(5\).

### Step 4: Evaluate Option 4
Option 4 is \(45 \div -9\).
- Calculation:
\[ 45 \div -9 = -5 \]
- Result: The value of Option 4 is \(-5\).

### Step 5: Compare the Results
Now we compare the values obtained from each option:
- Option 1: \(-5\)
- Option 2: \(-5\)
- Option 3: \(5\)
- Option 4: \(-5\)

### Conclusion
The values of Options 1, 2, and 4 are all \(-5\), while the value of Option 3 is \(5\). Therefore, Option 3 is different from the others.

### Final Answer
The answer is **Option 3**.
