Descartes's logical bit of algebra is on news (8)

Ross

I believe the answer is:

raisonne

'descartes's logical' is the definition.
('logical' in French, eg for Rene Descartes )

'bit of algebra is on news' is the wordplay.
'bit of' indicates a hidden word.
'RAISONNE' is hidden in the letters of 'algebra is on news'.

(Another definition for raisonne that I've seen is " presented logically".)

I've seen this clue in The Guardian.
