Have you ever made a mistake while drawing on a computer tablet and hit the "undo" button? Believe it or not, that helpful little button is actually using a thousand-year-old math trick called an inverse! Join Mira and Finn as they explore the magical mathematical moves that let you rewind time and put things back exactly the way they were! From taking three steps backward to solving a messy Rubik’s cube, almost every move in math has a secret twin that undoes it. You'll travel back to the bustling city of Baghdad in the year 820 to meet a brilliant scholar named al-Khwarizmi. He figured out how to use inverses to restore balance to puzzles, calling his method "al-jabr"—which is where we get the word algebra today! Discover why algebra is really just about putting broken things back together, and find out what happens when you multiply a number by zero. (Hint: it's a lot like trying to unscramble a raw egg!). Tune in to unlock the power of the mathematical undo button!
