EXPANDING
NUMBERS
What
Are
Expanding
Numbers?
•
An
expanding
number
is
taking
a
larger
number
apart
and
showing
each
number’s
total
value.
How
to
Expand
Numbers:
•
Think
of
the
place
value
of
each
digit
in
a
number.
•
Take
each
digit
out
of
the
number
and
add
the
appropriate
number
of
zeros
after
it
so
that
it
keeps
its
value.
For
example:
3,184
The
number
three
is
in
the
thousands
place.
If
the
three
is
taken
out
of
the
number,
three
zeros
need
to
go
behind
it.
The
three
will
then
look
like
this:
3,000.
Continue
on
like
this
with
all
the
digits
in
the
number.
These
values
all
need
to
be
added
together.
The
three
has
been
taken
out
and
made
into
3,000.
Next
is
the
number
1.
Since
this
number
is
in
the
hundreds
place,
it
turns
into
100.
The
number
8
will
become
80
since
it
is
in
the
tens
place.
The
number
4
will
stay
the
same
since
it
is
in
the
ones
place.
Therefore,
the
number
3,184
in
expanded
form
is
3,000
+
100
+
80
+
4.
