I'm writing some of my proofs up in french in order to practice the language and I have a few questions for any of you french speakers out there. First, what voice is generally used 'nous' or 'on'. Second when I am telling the reader to perform this or that mathematical procedure, do I use the imperative or the infinitive? Also if there are some other common mistakes anglophones make when writing math in french, please let me know, thanks! =].
