Another formula

Dear Editor,

Mr Clement Rohee, Minister of Home Affairs asserted that KN + SN +RR +KR + MN is equal to zero. My formula (I am not sure whether it is algebraic or chemical) is CR + CR + CR is equal to minus minus zero. I leave it to the mathematicians to work out what CR is equal to. Is there anything lower than zero? I know my friends in North America complain in the height of winter of below zero temperatures. Is there an analogy here?

Yours faithfully
