Hi Cong,

The question is asking you to decrement the value, not what 'unstable' should now equal. Each question is unique but they are just showing previous for reference.

Decrement is minus, so the reverse of unstable++;

Sorry for being cryptic, I'm trying to help without giving you the answer. :)
