kStacks
This calculator uses memory areas, called “stacks,” to temporarily store values (numeric stack) and commands (com- mand stack) according to their precedence during calcu- lations.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.
•Example:
1 2 3 4 5
1 | 2 | 3 | 4 |
| 5 | 6 | 7 |

•Calculations are performed in sequence according to “Order of Operations.” Commands and values are de- leted from the stack as the calculation is performed.
