OPERATION/EXAMPLE
Find
the
sum of
X
and X2 when
X has
values
of 3, 4,
8, and
11.
REMARKS
The
sum of
the X
values
is 26
as obtained
by
recalling
the
right
adder.
The sum
of the
X2 values
is
2 l0 as
obtained
by recalling
the
left
adder.
NOTE:
The PROD
ACCUM
and MULT
ACCUM
switches
using the
two
independent
adders
(AL
& AR) allow
the accumulation
of EX,
and
t X with
a single
keystroke
per
variable.

NOTE:
It is
important
to turn
off all
accumulation
switches after the
the
data has
been entered.
This is normally
necessary
in
the
final
calculations
as in the
example for
