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.

and three, people wrote 6 3. The space was there to mean "not any" tens. Sometimes people did not
remember the space. It was hard to see and to read.

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.
    Now zero has many important uses. Zero tells how many. Can you tell some other ways zero is
used?
