Fibonacci Leonardo Pisano, better known as Fibonacci, was an Italian mathematician of the 13th Century who helped introduce the Arabic numerals to Europe. Fibonacci's father was a diplomat, and as a result he was educated in Algeria, where he was taught the ten-digit decimal system we use today, and traveled widely in his youth. In 1202, Fibonacci, before the invention of the printing press, wrote Liber Abaci (Book of the Abacus), which was based on arithmetic …showed first 75 words of 412 total…

Fibonacci’s numbers have even been applied in architecture – the famous ancient Greek temple, the Parthenon, was built in a proportion that is the ratio between the Fibonacci numbers (approx. 1.618). Leonardo Fibonacci’s discoveries in maths, particularly his part in spreading the Arabic numeral system and discovering the Fibonacci sequence, have certainly had a significant effect on mathematics and even in architecture and art.
