Fibonacci

Hello! My name is Leonardo, but many people know me as Fibonacci. I was born in a city called Pisa in Italy a very, very long time ago, around the year 1170. My father was a merchant, which means he traveled to sell things. I loved to travel with him! Traveling showed me so many new and exciting things, especially my favorite thing in the whole world: numbers!

On my travels, I saw a new way to write numbers. Instead of using clunky letters like the Romans did, people in other lands used simple symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. It was like a secret code for counting! I thought this was the best idea ever. When I came home, I wrote a book in 1202 called Liber Abaci to show everyone in Europe how to use these new, easy numbers. It made doing math so much faster and more fun for everyone.

I also discovered a super special pattern. It starts with 1 and 1, and then you add the last two numbers to get the next one. Like this: 1, 1, 2, 3, 5, 8... Do you see it? The amazing part is that this pattern is hidden all over nature! You can find it in the number of petals on a flower, the spiral of a seashell, and even the shape of a pinecone. Numbers help us see the beauty of the world.

I lived a long and happy life full of numbers, for about 80 years. Even though I am not here anymore, the numbers I shared are used by everyone, every single day. And the special pattern I found is still studied by people who love math and nature. My work helped people see that numbers aren't just for counting—they are a magical part of our world.
