Mathematical operation (5)

Ross

I believe the answer is:

minus

'mathematical operation' is the definition.
(I know that minus is a type of arithmetic operation)

This is all the clue.

(Other definitions for minus that I've seen before include "Negative arithmetic operation" , "Take-away (sign)" , "'Take away' sign" , "Deprived of" , "(Of temperature) below zero" .)

I've seen this clue in The Guardian.
