But by writing his book, Leonardo Bonacci, Fibonacci, Bigollo Pisano jumpstarted (to use a term he wouldn’t understand) a process that otherwise might have dragged on for many more centuries.

In 1202 Leonardo da Pisa (aka Fibonacci) taught Western Europe how to do arithmetic with Arabic numerals. In Man of Numbers: Fibonacci's Arithmetic Revolution, Keith Devlin describes how basic ...

If the name “Fibonacci” doesn’t ring a bell for you, then just think back to the first “tricky” number sequence you ever saw in math class. It goes like this: The first 15 terms of the ...

It sprang from the mind of the 13th century Italian mathematician Leonardo Pisano, or Fibonacci. The sequence itself is derived from a math problem: If you put a pair of newly born rabbits – one male ...

Other key Fibonacci retracement levels include 23.6%, which results from dividing a Fibonacci number by the integer three places to the right, and 76.4%, which is found by subtracting 23.6 from 100.
