This calculator is specially equipped with the Algebraic Operating System This advanced system allows key sequences to be interpreted correctly by storing certain quantities and operations until the algebraic principles say they can be completed.

ARITHMETIC
FUNCTIONS
To
perform
simple
addition,
subtraction,
multiplication
or
division.
the
calculator
with
its
algebraic
type
of
entry
allows
you
to
key
in
the
problem
rust
as
it
is
stated.
This
calculator
is
specially
equipped
with
the
Algebraic
Operating
System
This
advanced
system
allows
key
sequences
to
be
interpreted
correctly
by
storing
certain
quantities
and
operations
until
the
algebraic
principles
say
they
can
be
completed.
A
more
complete
discussion
of
this
system
occurs
later
in
this
section
It
is
a
safe
procedure
to
press
the
key
before
the
start
of
each
new
problem
This
process
is
not
required
when
the
previous
problem
used
to
obtain
the
final
result
Following
n
with
a
numeric
entry
automatically
clears
the
previous
result

that

are

in
the
same

as
they
are
mathematically
stated.
