Fibonacci was one of the most important mathematicians of the Middle Ages. He was the person who first realized the implications of the Arabic numeral system and promoted it with his publication of Liber Abaci, which described it. If you want to understand the implications, try figuring out what you get when you divide CXXIV by XXXI, entirely in Roman numerals, then understand that was the only system medieval merchants had available until Fibonacci's book appeared.
Fibonacci also did a fair amount of original work in mathematics, publishing a number of books. There is a link to an article on him below.
A person was considered old when they were in their 40s.
Yes, it was common and often considered a compliment
No. 1994 is considered mid-'90s with 1995 and 1996. The exact middle of the 1990s is January 1, 1995. That implies 1993 is as close to the middle as 1996. (This is why 1993 is also sometimes considered mid-'90s.) And it implies 1994 is as close as 1995 to the middle. If you're dividing the '90s between early and late, and not considering a middle, then you'd place 1994 in the early section. (The early '90s would thus be 1990 to 1994, and the late '90s would be 1995 to 1999.) But this is rarely done.
Merchants, doctors, professors, lawyers, and some prosperous tradesmen were considered to be middle class in the British Colonial period in America
Since the middle ages had no knowledge of the brain or its functions there were several ideas about intelligence and the soul. The heart was considered to be one of the places where these were located.
He was born in c. 1170. Here are some details about him.Leonardo of Pisa also known as Leonardo Pisano, Leonardo Bonacci, Leonardo Fibonacci, or, most commonly, simply Fibonacci, was an Italianmathematician, considered by some "the most talented mathematician of the Middle Ages".

Fibonacci was a Renaissance mathematician who was revered as "the best mathematician of the middle ages.
Fibonacci's mother was Alessandra Bonaci who sadly died when Leonardo Fibonacci was 9.
Leonardo Fibonacci
The Italian mathematician, Leonardo Bonacci, who was better known by his nickname, Fibonacci, published a book entitled "Liber Abaci" at the start of the 13th Century. Through this he introduced European mathematicians to the sequence which would later bear his name. However, the sequence itself had appeared books published by Indian scholars at least 50 years previously. So the latest is the middle of the 12th Century.
Leonardo Pisano Bigollo, known as Fibonacci, was an Italian mathematician. Some say he was the most brilliant mathematician to live during the Middle Ages.
to educate physicians, astronomers and mathematicians.
The renowned Middle Ages mathematician's REAL NAME was Leonardo Pisano Bigollo (c. 1170 - c. 1250), but he was known by many names, such as Leonardo of Pisa, Leonardo Pisano, Leonardo Bonacci, Leonardo Fibonacci, and just plain Fibonacci.
he did not have college back in the middle ages so when he was travling with his fatherr is when was learning about math
Leonardo Pisano Bigollo (c. 1170 - c. 1250) - known as Fibonacci, and also Leonardo of Pisa, Leonardo Pisano, Leonardo Bonacci, Leonardo Fibonacci - was an Italian mathematician, considered by some "the most talented western mathematician of the Middle Ages."Fibonacci is best known to the modern world for the spreading of the Hindu-Arabic numeral system in Europe, primarily through the publication in 1202 of his Liber Abaci (Book of Calculation), and for a number sequence named the Fibonacci numbers after him, which he did not discover but used as an example in the Liber Abaci.Leonardo Fibonacci was born around 1170 to Guglielmo Bonacci, a wealthy Italian merchant. Guglielmo directed a trading post (by some accounts he was the consultant for Pisa) in Bugia, a port east of Algiers in the Almohad dynasty's sultanate in North Africa (now Béjaïa, Algeria). As a young boy, Leonardo traveled with him to help; it was there he learned about the Hindu-Arabic numeral system.Recognizing that arithmetic with Hindu-Arabic numerals is simpler and more efficient than with Roman numerals, Fibonacci traveled throughout the Mediterranean world to study under the leading Arab mathematicians of the time. Leonardo returned from his travels around 1200. In 1202, at the age of 32, he published what he had learned in Liber Abaci (Book of Abacus or Book of Calculation), and thereby popularized Hindu-Arabic numerals in Europe.Leonardo became an amicable guest of the Emperor Frederick II, who enjoyed mathematics and science. In 1240 the Republic of Pisa honored Leonardo, referred to as Leonardo Bigollo, by granting him a salary.Fibonacci died in Pisa, but the date of his death is unknown, with estimates ranging from 1240 to 1250.In the 19th century, a statue of Fibonacci was constructed and erected in Pisa. Today it is located in the western gallery of the Camposanto, a historical cemetery on the Piazza dei Miracoli.
Mathematicians in ancient India s invented the decimal system around in the 9th century CE. It was later adopted by Persian and Arabic mathematicians and spread to the western world by the High Middle Ages.
