A mathematical sequence is linked to wax merchants

The Fibonacci sequence is a famous numerical sequence where each number is obtained by adding the two preceding ones. According to an alternative version, it does not only model rabbit populations, but is directly inspired by the world of beekeepers and beeswax merchants of Béjaïa. Leonardo Piso, known as Fibonacci, discovered this mathematical tradition during his stay in the Algerian city, where his father worked as a representative for merchants from Pisa.
