Before
the
invention
of
written
numbers,
people
used
many
different
ways
to
count
things.

Third-reading
At
first,
people
used
their
fingers,
and
even
their
toes.
However,
they
could
only
count
small
numbers
in
this
way.
Try
to
retell
the
text
by
yourselves.
After
that,
they
began
to
make
small
marks
on
sticks
and
bones.
This
helped
them
count
bigger
numbers.
Then
people
began
to
use
tokens
made
from
clay
or
small
stones.
They
often
put
the
tokens
on
pieces
of
string.
This
helped
them
count
even
bigger
numbers.
This
developed
into
tools
like
abacus.

Finally,
people
began
to
develop
systems
of
written
marks
to
show
different
numbers.
It
is
called
the
Hindu-Arabic
system.
