The publication of Liber Abaci, Leonardo Pisano's book of calculation, in 1202 introduced the use of the Hindu-Arabic numeration system across Europe. The techniques of arithmetic and problem solving explained here were drawn from Leonardo's education and travels throughout the world of the late 12th century. Leonardo, who was also known as Fibonacci, wrote several books on mathematics following the Liber Abaci. While not widely appreciated, this work along with Fibonacci's other writings, played an important first role in reviving mathematics in Europe. In this talk we will examine some of the techniques introduced in the Liber Abaci and explore some of the problems presented there using both his methods and those of contemporary algebra. We will also look at some of the techniques presented in this book from 1202 that are still in use today.
