Fibonacci who?!?

---

1170-1250

• Leonardo Pisano was a famous mathematician who wrote under the name of Fibonacci.
• In 1170, he was born in the town of Pisa, Italy.
• He was educated in North Africa and studied mathematics in Bugia (now called Bejaia, which is in Algeria).
• He spent a major part of his life traveling with his father, and from this traveling, he saw the advantages of the different mathematical systems used in each country.
• He wrote the book Liber Abaci, which means "Book of Calculating," and it introduced the Arabic numerals  and the Hindu-Arabic place-valued decimal system to the Western culture.
• The first known recording of Fibonacci's Sequence is in this book, and is shown through the famous rabbit problem.

Fibonacci's Seguence is the sequence formed by adding the previous two numbers.

0+1 = 1
1+1 = 2
1+2 = 3
2+3 = 5
3+5 = 8
 . . .

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, . . .
