Can anyone explain what this means?

Question

Consider the following code which is supposed to add a value passed to the method to an instance variable; however, there is a problem. Re-write this code, without renaming any variable names, to resolve the problem.
private int number = 123;
public void addNumbers (int number)
number = number + number;
System.out.println("The local variable is: " + number);
System.out.println("The instance variable is: " + number);
}

So explaining the question.

2. Look at the code.
3. Figure out what is wrong.
4. Explain the fix needed to make it work.

That phrase. What does it mean by renaming any variable names?The underlined parts are variable names. You cannot change those.
private int number = 123;
public void addNumbers (int number)
