4B Life Leonardo da Pisa or Leonardo Pisano Don’t be confused with Leonardo da Vinci!! Born: 1170 Pisa Italy

Died: 1250 Pisa Italy

Better known as FIBONACCI

Which means “son of Bonaccio” He lived in North Africa

where he received an education from the Moors an Arabic people. HE WAS THE GREATEST MATHEMATICIAN FROM

THE MIDDLE AGE He was one of the first people to introduce the Hindu Arrabic system to Europe. This is the positional system we use today

(decimal system), with the digits 0 to 9 and a decimal. It talks about the decimal system and the fibonacci numbers He Wrote the famous book: Liber Abaci FIBONACCI NUMBERS The Fibonacci numbers are a sequence of numbers that all have a very specific relationship with each other.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55……. In math a sequence is a list of numbers arrange in a particular order.

Example:

A sequence of whole numbers is: 1,2,3,4,5,6,7…………… You can get the Fibonacci sequence by adding the previous two numbers starting with 0 and 1 RABBIT EXPERIMENT In his book "Liber Abaci" (book of calculation), Fibonacci post the following problem: If you put a pair of new born rabbits (male and female) in a closed place, how many pairs of rabbits will there be after 1 year? They become productive when they are 1 month old. The gestation process takes 1 month.

A female can give birth every month. It will always be one male and one female rabbit.

New born rabbits never die.

CONSIDERATIONS As you can see our results up to now show a Fibonacci sequence. So if we continued the sequence until we had 13 numbers we would get the results of this experiment. The Answer is 233 Fibonacci probably didn’t invent the rabbit problem but he made it so popular that eventually became associated with him and the number sequence that now bears his name.
