Ans.
Note
that
power
calculations have
priority over the four arithmetic
calculations.
Also
note that
powers of a
negative
number do not compute. This
is
due to the
calculation
process used by
the Pocket
Computer.

Calculations
with
parentheses
Calculations can
be
performed by using the
i
<
I
and
i

keys
in the same manner
as
you use
parentheses
in mathematical
formulas.

Ans.
The
use
of parentheses results in
different calculation sequences as
follows.
Take
special care
when multiplying,
dividing or extracting
square
roots.
