Pierre de Fermat

Hello! My name is Pierre de Fermat. I was born in a beautiful town in France a very long time ago, on August 17th, 1607. When I grew up, my job was to be a lawyer, which meant I helped people with the rules of the land. But my biggest passion, my favorite thing to do, was mathematics! To me, numbers weren't just for counting—they were part of exciting puzzles and secret codes waiting to be solved.

I never worked as a professional mathematician; I did it all for fun in my spare time! I would scribble ideas and solve problems whenever I had a free moment. I didn't write books about my discoveries. Instead, I shared them in letters with other thinkers. In 1654, I wrote to my friend Blaise Pascal. We talked about games of chance, like flipping a coin. Our ideas helped start a whole new kind of math called probability, which helps us figure out how likely something is to happen.

One day, around the year 1637, I was reading a math book and had a brilliant idea. I came up with a very tricky number puzzle. I was so sure I had solved it! I wrote a little note in the margin of the book that said, 'I have a truly marvelous proof of this, which this margin is too narrow to contain.' I never wrote the full answer down, so my little note became a famous mystery for other mathematicians to solve.

I lived to be 57 years old, and my puzzle, which became known as 'Fermat's Last Theorem,' challenged the smartest minds for more than 350 years! It was finally solved long after I was gone. I am remembered today as the 'Prince of Amateurs' because I showed the world that you don't have to be a professional to have amazing ideas that can change everything. All you need is a curious mind and a love for puzzles.
