A very happy belated Pi(e) Day from mathdeptatcsu, who celebrated in style! 🥧 Pi(e)ing your professors and supporting a good cause? Count us in! This past Tuesday, donations supported both the pi(e)ing of your favorite math professor as well as the CSU chapter of the American Mathematical Society. #PiDay #PiDay2023 #AmericanMathematicalSociety #ColoradoState
