Did Leonardo Fibonacci work with anyone else?

Leonardo Fibonacci, known for introducing the Fibonacci sequence to the Western world, primarily worked independently. However, he was influenced by earlier mathematicians, especially those from the Islamic Golden Age, such as Al-Khwarizmi, whose works on arithmetic and algebra shaped Fibonacci's understanding. While there’s no record of him collaborating directly with others, his writings reflect the mathematical knowledge of his time, suggesting a broader intellectual community.
