Calculus isn't every student's forte, but even those who are more grammar nerds than number whizzes can appreciate the inspiring talent of people that can answer complicated equations without scribbling on scratch paper or counting off on fingers and toes. We have a soft spot for movies that delve into the complicated head of math geniuses. With trademarks like frantic chalkboard formula solving and "aha!" moments of numeral clarity, these films are ideal to watch the next time you're nostalgic for algebra.
