After the first month only the original pair remains since rabbits can't reproduce until they a¬re at least one month old. ¬At the start, two newborn rabbits are placed in a fenced-in yard and left to breed. This thought experiment artificially dictates that the female rabbits always give birth to pairs consisting of one male and one female. In the book, Leonardo pondered the question: Given ideal conditions, how many pairs of rabbits could be produced from a single pair of rabbits in one year? The answer, it turns out, is 144 ¬- and the relationship used to obtain that answer is, you guessed it, the Fibonacci sequence. The text laid out the Hindu-Arabic arithmetic useful for tracking profits, losses, remaining loan balances, etc, introducing the Fibonacci sequence to the Western world.

It was a “cookbook” written for tradespeople on how to do calculations.

Keith Devlin, the author of Finding Fibonacci: The Quest to Rediscover the Forgotten Mathematical Genius Who Changed the World, says there are ancient Sanskrit texts that use the Hindu-Arabic numeral system - predating Leonardo of Pisa by centuries.īut, in 1202 Leonardo of Pisa published a mathematical text, Liber Abaci. In the 19th century, historians came up with the nickname Fibonacci (roughly meaning 'son of the Bonacci clan') to distinguish the mathematician from another famous Leonardo of Pisa. 1170, was initially known as Leonardo of Pisa. The Italian mathematician, who was born around A.D. Many sources claim this sequence was first discovered or 'invented' by Leonardo Fibonacci. The Fibonacci sequence is the series of numbers where each number is the sum of the two preceding numbers.
