This story in verse tells how the number 1 goes out to make friends because he feels lonely. He crosses valleys, rivers and deserts where he finds the rest of the numbers from 0 to 9. The journey is long and is not exempt from disappointment and dangers. In the end, the character-number obtains what he seeks through hard work and effort. Each number represents a different character.
