# Fibonacci Thief!

**Leonardo Pisano****, known as Fibonacci, **was an Italian mathematician, considered to be the **m**ost talented mathematician of the Middle Ages. One of Leonardo's m**a**thematical formulas that he is most famous for is **t**he *Fibonacci Sequence.*

The *Fibonacci Sequence* is calculated by the fact t**h**at every number after the first two is the sum of the two preceding numbers:

### 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144

### For example - 144=89+55 OR 34=21+13

This formula isn't just used in math, either! It is seen in many things around you - from the arrangement of leaves on a tree, to the way sunflower seeds are laid out on the flower!
