Calculation Stacks
This calculator uses memory areas, called "stacks", to temporarily store numeric value (numbers) and commands (+ – x ...) 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 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.
Order of Operations
In the same precedence level, calculations are performed from left to right.
Operation enclosed within paredtheses is performed first. When a calculation contains an argument that is a negative number, the negative number must be enclosed within parentheses.
Example:
