Leonardo Fibonacci was an Italian mathematician born around 1170 in Pisa, Italy. He introduced the Indo-Arabic numeral system to Europe, which uses positional notation with the numbers 0 through 9. He is also known for the Fibonacci sequence, where each number is the sum of the two preceding numbers. Fibonacci wrote several books on mathematics, including one at age 32 introducing the concept of zero and the Indo-Arabic numeral system to Europe. He died around 1250 in Pisa.

1. Leonardo Fibonacci
He introduced the
Indo-Arabig
numeration system
in Europe.
He was born in
c.1170
He died in c.1250
He was born in Pisa,
Italy and was
catholic.

2. What did he do?
He introduced the Indo-Arabig numeration
system in Europe that we use actually with a
posicional notation from 1 to 9 and a number
with a nule valor: 0. He invented the Fibonacci
succession, that consisted to start by the 0 and
1 and obtain the next term plusing the two
previous numbers.

4. How did he know mathematics?
His father was the consul of Pisa in Africa, so
Leonardo travelled to Africa for to help his
father and was there where he know the IndoArabig system.
He went to Mediterranean countries to work with
the most highlight mathematics in that time.

6. Books
*When he was 32 he wrote a book in the wich
he talked about the zero and the Indo-Arabig
system.
*The second book talk about the dimensional
geometry.
*This book contain a series of problems to
resolve.
*It contains two problems proposed to the
astrologer Teodoro.
*It's a book that contains problems proposed to
Teodoro like the last time, but are more dificult.
