10 Addition (+), subtraction (−)
If a calculation contains a negative value, you may need to enclose the
negative value in parentheses. If you want to square the value -2, for
example, you need to input: (-2)
2
. This is because x
2
is a function
preceded by a value (Priority 3, above), whose priority is greater than the
negative sign, which is a prefix symbol (Priority 5).
Example:
2 -2
2
= -4
2 (-2)
2
= 4
Stack Limitations
This calculator uses memory areas called stacks to temporarily store lower
calculation priority sequence values, commands, and functions. The
numeric stack has 10 levels and the command stack has 24 levels, as
shown in the illustration below.
A Stack ERROR occurs when the calculation you are performing causes
the capacity of either stack to be exceeded.
Calculation Ranges, Number of
Digits, and Precision
The calculation range, number of digits used for internal calculation, and
calculation precision depends on the type of calculation you are
performing.
