Leonard Fibonacci introduced Liber abaci, which means “The Book of calculations.” Fibonacci was best known for a series of numbers which were introduced in Liber abaci, and later named the Fibonacci sequence in his honor. The sequence begins with 0 and 1. After that, use the simple rule: Add the last two numbers together to get the next. 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377… In Fibonacci's day, mathematical competitions and challenges were ordinary. In 1225 Fibonacci took part in a tournament at Pisa ordered by the emperor at the time, Frederick II. During this competition the following problem arose: Beginning with a single pair of rabbits, if every month each productive pair bears a new pair, which becomes productive when they are fibonacci, sequence, pair, number, liber, abaci, time, seeds, rabbits, productive, problem, petals, numbers, month, look, introduced, every, day, appear, after, 89, 55, 34, write, way, unrealistic, two, tournament, took, together, today, sunflower, stem, spirals, spiral, single
