Calculation Stacks

This calculator uses memory areas, called "stacks", to
temporarily store numeric value (numbers) commands (+, –,
x...) and functions according to their precedence during
calculations.
The numeric stack has 10 levels and command stack has 128
levels. A stack error [Stack ERROR] occurs whenever you try
to perform a calculation that exceeds the capacity of stacks.
Calculations are performed in sequence according to "Order
of Operations". After the calculation is performed, the stored
stack values will be released.
