ADVANCED/
“SLIDE
RULE”
KEYS
In
this
section
we
move
on
to
discuss
some
of
the
features
of
your
calculator
that
are
especially
helpful
in
engineering,
scientific,
and
more
advanced
mathematical
applications
(applications
that
not
too
long
ago
used
to
be
handled
with
mechanical
slide
rules
and
tables).
Many
of
these
features
have
only
been
made
possible
by
more
recent
developments
in
Integrated
Circuit
(IC)
Technology.
These
new
developments
allow
calculator
designers
to’put”
various
functions
and
tables
right
into
the
IC
chip.
This
way
you
can
put
the
calculator
to
work
on
a
complex
calculation
with
the
touch
of
a
key.

Notation
Key
In
many
applications,
particularly
in
science
and
engineering,
you
may
need
to
calculate
with
extremely
large
or
small
numbers.
Such
numbers
are
easily
handled
(by
both
you
and
your
calculator)
using
scientific
notation.
A
number
in
scientific
notation
is
expressed
as
a
base
number
(or
“mantissa’’)
times
ten
raised
to
some
power
(or
exponent”),
owe’
Mantissa
x
i0P
.
To
enter
a
number
in
scientific
notation
e
Enter
the
mantissa
(then
press
Hil
it's
negative.)
°
Press
[fe]
(Enter
Exponent)
—
a
"00"
will
appear
at
the
right
of
the
display.
Enter
the
power
of
10
(then
press
if
it's
negative.)
A
number
such
as
—3.8901448
x
10-*?
will
look
like this
in
your
display:
mantissa
exponent
decimal
point
decimal
exponent
sign
floating
minus
sign
In
scientific
notation
the
power
of
ten
(the
two
digits
to
the
right
in
your
display)
tells
you
where
the
decimal
point
would
have
to
be
if
you
were
writing
the
number
out
in
longhand.
A
positive
exponent
tells
you
how
many
places
the
decimal
point
should
be
shifted
to
the
right,
a
negative
exponent
—
how
many
places
to
the
left.
For
example:
2.9979
x
10°
equals
2,99790000
