Fibonacci was one of the most talented mathematicians in the Middle Ages. Few people realize that it was Fibonacci that gave us our decimal point when during fractions or other Math problems. When he Fibonacci was studying mathematics, he used the Hindu-Arabic symbols instead of Roman symbols which didn’t have zeros and lacked place value. Fibonacci also created the Roman numeral system. It's no wonder that such a system caught on so quickly with merchants and other people in professions where day-to-day use of mathematics was essential. With the new system, people could compute sums and differences more quickly, giving them a competitive edge. Fibonacci realized the advantages of this new system, as did most who were exposed to it, so when he returned to Pisa, he wrote a book about it that he finished in 1202. Titled Liber abbaci, meaning "Book of Calculating," the work dealt with the methods of arithmetic in the decimal system (now taught to all elementary school children) and it eventually persuaded European mathematicians to drop the old way in favor of the new. Another famous problem Fibonacci created was Rabbits and and Bees. How fast rabbits could breed in ideal circumstances. Suppose a newly born pair of rabbits, one male and one female are put in a field. Rabbits are able to mate at the age of one month so that at an end of its second month a female can reproduce a second pair of rabbits. The rabbit problem is obviously very contrived, but the Fibonacci sequence does occur in real populations. Honeybees provide an example. In a colony of honeybees there is one special female called the queen. The other females are worker bees who, unlike the queen bee, produce no eggs. The male bees do no work and are called drone bees.
Males are produced by the queen's unfertilized eggs, so male bees only have a mother but no father. All the females are produced when the queen has mated with a male and so have two.
