Im not sure what the question was exactly but if you want to auto decrement a variable it would be

int unstable = 25; unstable --; //Post-decrement OR --unstable; //Pre decrement

so what do u think will be the value of the variable UNSTABLE.........is it 21 ????

Based on what you have said above; int unstable = 25; unstable -= 5; unstable++; -> This would result in 25-5+1

If you were using decrement it would result in -> 25 - 5 - 1

Just follow the operators and think of it logically :)

Thank you so much Jayden!!
