Definition
未知数 is a noun meaning 'unknown quantity' — it can be literal (a variable in math) or figurative (an uncertain outcome). Unlike 默默无闻 (obscure, a nobody) or 不得而知 (unable to find out, nobody knows), 未知数 focuses on the thing itself being unknown or unpredictable, not on a person's status or the act of not knowing.
