Fermat's Last Theorem

Fermat's Last Theorem

Fermat’s Last Theorem is a fun math puzzle that has excited people for hundreds of years. It is about numbers and shapes. The puzzle asks if you can find three whole numbers—a, b, and c—that make the equation a^n + b^n = c^n true when n is bigger than 2. For n = 1 and n = 2, there are many answers, but for higher numbers, it seemed impossible for a long time.

The problem was first written down by a clever man named Pierre de Fermat in 1637. He wrote it in a book called Arithmetica. Fermat said he had a proof but it was too big to write in the small space he had. For over 350 years, many smart people tried to solve it but could not.

Finally, in 1994, a mathematician named Andrew Wiles found the answer. His work not only solved Fermat’s puzzle but also helped prove other important ideas in math, like the modularity theorem. Because of this amazing work, Wiles received the Abel Prize in 2016.

Fermat’s Last Theorem shows how one big question can help math grow and inspire new discoveries. It is a wonderful example of how puzzles can bring people together across time to solve big challenges.
