Leonardo Pisano Fibonacci
Childhood
 It is believed that Leonardo Pisano Fibonacci was
born in the 13th century, in 1170. Fibonacci was born
 in Italy but obtained his education in North Africa.
   Very little is known about him or his family and
there are no photographs or drawings of him. Much
     of the information about Fibonacci has been
  gathered by his autobiographical notes which he
                  included in his books.
Accomplishments

    Fibonacci is considered to be one of the most
     talented mathematicians for the Middle Ages.

 Few people realize that it was Fibonacci that gave us
  our decimal number system, which was replaced by
      Roman Numeral system as times advanced.
Liber abaci
 Liber abaci is his book were he shows how to use our
        current numbering system all from what he
                        discovered.
     Here is an example problem form his book :A
        certain man put a pair of rabbits in a place
 surrounded on all sides by a wall. How many pairs
  of rabbits can be produced from that pair in a year
 if it is supposed that every month each pair begets a
 new pair, which from the second month on becomes
                       productive?
Liber abaci continued
 The problem that you just read was the problem that lead
    to this following discovery of the introduction of the
        Fibonacci Numbers the Fibonacci Sequence.
   The sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55... This
 sequence, shows that each number is the sum of the two
 preceding numbers. It is a sequence that is seen and used
 in many different areas of mathematics and science. The
    sequence is an example of a recursive sequence. The
   Fibonacci Sequence defines the curvature of naturally
     occurring spirals, such as snail shells and even the
             pattern of seeds in flowering plants.
Contributions
 Fibonacci is famous for his contributions to number
                          theory.
  In his book, Liber abaci he introduced the Hindu-
   Arabic place-valued decimal system and the use of
              Arabic numerals into Europe
    He introduced us to the bar we use in fractions,
     previous to this, the numerator has quotations
                         around it.
 The square root notation is also a Fibonacci method.
