Long, long ago there was no zero. To write the number sixty-three people wrote 6 3. To write six hundred and three, people wrote 6 3. The space between six and three was there to mean." not any "tens. Sometimes people did not remember the space. It was hard to see and read.
Later people used a dot to hold the space. Six hundred and three looked like this 6.3. But the dot was hard to see. So people put a circle around it like this 6⊙3.
Then people could see the dot. They remembered the space. At last, only the circle around the dot was used. It was like a zero. This is one story of how the zero came to be used.
