History of Digits

Roman abacuses or stone tokens were employed thousands of years ago when people were not familiar with the numerical system. The need for larger denominations was recognised as time passed and trade between nations and regions advanced. The development of number systems as we know them today was a result of this. The need to deal with larger numbers also emerged as the nations advanced. The size of a bacterium, the distance between the earth and the moon, and other wonders inspired us to develop larger number systems. As a result, the idea of numbers and digits was introduced.
