Can the mane six discover calculus fast enough to win a flying competition, counter a deadly parasite, and destroy a tornado?

Welcome to the only MLP fanfiction which doubles as a calculus tutorial.

Once this fic is complete, it will serve as a complete walkthrough for calculus. I want to teach the intuitive side of math: tell you why things work, and make you feel like you could have discovered them yourself.

Petition your teacher to make this your school's standard textbook.
