Renee Descartes gave us some cool stuff. "I think, therefore I am." Whoa, deep. But what's also deep is his discovery about the sign changes in a polynomial. Using his Rule of Signs, we can uncover how many positive zeros, negative zeros, and imaginary zeros exist for any polynomial. Merci beaucoup, Monsieur Descartes, et YAY MATH!
