k Stacks
This calculator uses memory areas, called “stacks,” to tem-
porarily 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 (Stk ERROR) occurs
whenever you try to perform a calculation that is so com-
plex that the capacity of a stack is exceeded.
