When did Fibonacci become interested in math?

Answer 1

Unfortunately, we don't know a lot about his early life. His real name was Leonardo Pisano, and he was born in Pisa, Italy, around 1170 CE (some sources say 1175); he was the son of a wealthy merchant, and later went into business himself. We also know he did a lot of traveling, visiting Egypt, Syria, Greece, and other regions. But when exactly he decided to focus on mathematics rather than on business is not clear. We do know he began writing about math around 1202, when he would have been about 32 years old, but he probably had had an interest in the subject long before that.
