Can you tell me what's wrong with the code?

There is a mistake in the code with the subtraction operation. The second if statement for the subtraction operation should have the condition `answer == operand1 - operand2` instead of `answer == operand1 + operand2`. Here is the corrected portion of the code:

```python
elif operation == 1:
answer = int(input(str(operand1) + " - " + str(operand2) + " = "))
if answer == operand1 - operand2:
success = True
```

With this correction, the subtraction operation will work correctly in the code.
