Selon moi, cette formule est fausse.  According to me, this formula is false.
$$\mathrm{Selon}\:\mathrm{moi},\:\mathrm{cette}\:\mathrm{formule}\:\mathrm{est}\:\mathrm{fausse}. \\ $$$$\mathrm{According}\:\mathrm{to}\:\mathrm{me},\:\mathrm{this}\:\mathrm{formula}\:\mathrm{is}\:\mathrm{false}. \\ $$$$ \\ $$
