Scientific
Notation
Key
Many
scientific
and
engineering
calculations
involve
very
large
or
small
numbers
which
can
be
awkward
to
manipulate
Scientific
notation
makes
these
values
easier
to
handle
Any
number
can
be
expressed
in
scientific
notation
as
a
base
value
(mantissa)
limes
10
raised
to
some
power
(exponent).
For
example,
the
value
1.050.000
is
expressed
as
1
05
x
ICr
In
scientific
notation.
The
sign
(+
or
-)
of
the
exponent
indicates
where
the
decimal
point
is
placed
when
the
number
is
written
in
standard
form
A
positive
exponent
indicates
that
the
decimal
is
shifted
to
the
right
to
display
the
number
in
standard
format,
and
a
negative
exponent
indicates
that
it
Is
shifted
to
the
left
The
value
of
the
exponent
gives
the
number
of
places
the
decimal
point
Is
to
be
moved
