HISTORY OF NUMBERS

People have always been fascinated by NUMBERS... Numbers are actually basic elements of mathematics used for counting, measuring, ranking, comparing quantities, and solving equations.  

Today´s numbers, also called Hindu-Arabic numbers, are a combination of just 10 symbols or digits: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0. These digits are introduced in Europe within the XII century by Leonardo Pisano [aka Fibonacci], an italian mathematician. He was educated in North Africa, where he learned and later carried to Italy the now popular Hindu-Arabic numerals.
