Long, long ago there was no zero. To write the number sixty-three people wrote "63".To write six hundred and three, people wrote "6 3".The space (空格) between six and three was there to mean "not any tens"(没有十位数). Sometimes people did not remember the space. It was hard to see and read. Later people used a dot(点) to hold(占据) the space. Six hundred and three looked like this 6.3.But the dot was hard to see. So people put a circle(圆圈) 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.
