Numbers—Zero and Natural Number
1. Originally, people used natural numbers1 only to count the objects around them. Then, people in Greece, India, China and Mesoamerica2 began to study numbers as things in their own right3. Zero was not accepted as a number by Europeans until the 12th century. Although they accepted zero as a number, they did not consider it a natural number. In the nineteenth century, mathematicians developed a new definition of natural numbers. From this time on, zero has been considered one of the natural numbers.

Runs through my veins and in other seekers it penetrates My reason why The big city air smells so sweet Takes me through journeys in time From my youth to as far as I can see Visions of a sunset just appear when I close my eyes Takes me closer to heaven When the flute starts to fly And the violin cries It's all I need in my life It's all I need and no one Can take your place by my side
