 int unstable = 25;
    unstable -= 5;

    int unstable = 25;
    unstable -= 5;
    unstable++;
    // unstable = 21




    int unstable = 25;

Yep.

  1. int, 25
  2. 20
  3. unstable++
  4. unstable--
  5. /=

Remember, Mr. Turner put the multiplication symbol in front of the = sign, so they want you to use the same logic and put the / in front of =, so your answer is /=.

for which one there is 3 different questions ?

It is for the last one.

and the others

What do you mean by that?
