What
is a manual
calculation?
Normally
you'll
program the
Pocket
Computer in the
PRO mode
and
execute
programs in the
RUN or DEF
mode.
For problems that
don't need
programming,
you
can
Input
the necessary
data
in the RUN (or
DEF)
mode
and obtain
immediate
answers.
This
is called
the
Direct
Execution
mode
or
you
might
prefer to
call
it
the manual
calculation mode.

instructions:
•
Constant

n,
Exp
•
Sign +,
-
•
Arithmetic
operator +,
-,
*
(Multiplication),
/(Division),
A
(Power)
•
Logic operator

•
Memories A
-~
Z, A
(
)
An "Expression"
can
be made
by
combining
these
instructions according to
a
mathematical
formula.
A
mathematical formula is
defined
as
an
"Expression",
even if
it
is composed only of constants or
memories. (Eg.
12,
n,
A, etc).
