未知数 (wèi zhī shù) — (mathematics) unknown quantity; an unknown; something uncertain or unpredictable

定義

Literally 'unknown number' — its math sense (a variable in an equation) extends metaphorically to 'an unknown factor' (a person or outcome you can't predict). Unlike 不得而知, it names the unknown thing itself, not the inability to find out.
