Comparing
Whole
Numbers

Symbols
are
used
to
show
how
the
size
of
one
number
compares
to
another.


These
symbols
are
<
(less
than),
>
(greater
than),
and
=
(equals).

For
example,
since
2
is
smaller
than
4
and
4
is
larger
than
2,
we
can
write:
2
<
4,
which


says
the
same
as
4
>
2
and
of
course,
4
=
4.


• To
compare
two
whole
numbers,
first
put
them
in
numeral
form.


• The
number
with
more
digits
is
greater
than
the
other.


• If
they
have
the
same
number
of
digits,
compare
the
digits
in
the
highest
place
value


position
(the
leftmost
digit
of
each
number).
The
one
having
the
larger
digit
is

greater
than
the
other.


• If
those
digits
are
the
same,
compare
the
next
pair
of
digits
(look
at
the
numbers
to


the
right).


• Repeat
this
until
the
pair
of
digits
is
different.
The
number
with
the
larger
digit
is


greater
than
the
other.


Example:
402
has
more
digits
than
42,
so
402
>
42.


Example:
402
and
412
have
the
same
number
of
digits.


We
compare
the
leftmost
digit
of
each
number:
4
in
each
case.


Moving
to
the
right,
we
compare
the
next
two
numbers:
0
and
1.


Since
zero
is
less
than
one,
402
is
less
than
412
or
402<412.
