In the same precedence level, calculations are performed
from left to right.
I
Operations enclosed within parentheses are performed first'
When a calculation contains an argument that is a negative
number, the negative number must be enclosed within the
parentheses.
Example:
@ E E E
E @ E E @ E
F 2 ) 2 = 4

This calculator uses memory areas, called "stacks", to
temporarily store numeric value (numbers) commands (+,
-,
x... jand functions according to their precedence during
calculations.
I
The numeric stack has 10 levels and the command stack has
128 levels. A stack error [Stack ERROR] occurs whenever
you try to perform a calculation that exceeds the capacity of
stacks.
I
Calculations are performed insequence according to "Order
of Operations". After the calculation is performed, the stored
stack values will be released.
The calculator is locked up when an error message is shown on
the displav indicating the cause of the error.

Press O or O to display the input expression with the
cursor positioned next to the error.
