3 Stack This calculator uses memory areas, called “ stacks “, to temporarilystore values (numeric stack) and commands (command stack ) accord-ing to their precedence during calculations. The numeric stack has 10levels and command stack has 24 levels. A stack error (Stk ERROR)occurs whenever you try ...
