This calculator uses memory areas, called "stacks," to temporarily store values (numeric stack) and commands (command stack) according to their precedence during calculations. The numeric stack has 10 levels and the command stack has 24 levels. A stack error (Stack ERROR) occurs whenever you try to perform a calculation that is so complex that the capacity of a stack is exceeded.


Numeric Stack

Command Stack

Calculations are performed in sequence according to "Calculation Priority Sequence." Commands and values are deleted from the stack as the calculation is performed.
