单选题 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 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. Now zero has many important
uses. Zero tells how many. Can you tell some other ways of using zero?
