INPUTTING EXPRESSIONS AND VALUES
Input Capacity
F-715SG allows you to input a single calculation up to 79
steps.
Starting from the 73rd step, the cursor changes from [ _ ] to
[

need to input a single calculation with more than 79 steps,
you should separate your calculation into two or more
segments.
Input Editing
New input begins on the left of the upper (entry) line. As the
entries are more than 12 digits, the line will scroll to the
right consecutively.
Press

INPUT RANGE AND ERROR MESSAGE
Calculation Accuracy, Input Ranges
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:
–22 = –4
(–2)2 = 4
